Indophenol (C12H9NO2) is an organic compound characterised by its deep blue colour, which is a key indicator in various chemical reactions. It appears as a reddish-blue or dark green powder. Indophenol is primarily known for its chromogenic properties, meaning its ability to form a distinct colour, which makes it invaluable in analytical chemistry as a reagent for colourimetric assays.
 

Applications of Indophenol

• Analytical Reagent (Largest Share): The most significant application of Indophenol is in analytical chemistry. Its formation (often Indophenol Blue) is the basis of Berthelot's reaction, a widely used colourimetric test for the quantitative determination of ammonia and ammonium ions in various samples, including water, wastewater, and biological fluids. It's also used in assays for other compounds like paracetamol.
• Dye and Pigment Industry: Indophenol, as a deep blue dye, has seen historical use in textile dyeing and hair colouring. While modern synthetic dyes have largely replaced it in many mainstream applications, its chromogenic properties remain relevant for specific niche colouration needs.
• Research and Development: Used in chemical and biological research laboratories as a reagent or indicator for various experiments requiring colour change detection. For instance, dichlorophenol-indophenol (DCPIP), a related compound, is used to determine Vitamin C content.
• Biosensors and Redox Materials: Its redox properties make it relevant in the development of certain biosensors and as a component in redox-active materials.
   

Top 5 Manufacturers of Indophenol

The market for Indophenol, particularly for its analytical and niche dye applications, consists of fine chemical and laboratory reagent suppliers. Due to its specific uses, it is not produced on the same massive scale as commodity chemicals. Five prominent global manufacturers or suppliers include:

• Spectrum Chemical Mfg. Corp. (USA)
• Tokyo Chemical Industry Co., Ltd. (TCI) (Japan)
• Sigma-Aldrich (Part of Merck KGaA, Germany)
• Alfa Aesar (Part of Thermo Fisher Scientific, USA)
• Chem-Impex International, Inc.
   

Feedstock for Indophenol and Its Dynamics

The production of Indophenol through condensation primarily depends on p-nitrosophenol, carbazole, and sodium polysulfide as the key raw materials, with butanol serving as the solvent and concentrated sulfuric acid acting as the catalyst. The market conditions and supply factors influencing these feedstock components play a vital role in determining the overall production costs of Indophenol.

• p-Nitrosophenol (C6H5NO2): Its synthesis involves the nitrosation of phenol.
  • Phenol Market: The price and availability of p-nitrosophenol are linked to the global phenol market (derived from benzene and propylene) and nitric acid prices. Volatility in petrochemical markets can affect its cost, impacting the cash cost of production of p-Nitrosophenol, which in turn influences the pricing and supply of Indophenol.
  • Speciality Chemical: As a more specialised intermediate, its supply can be less elastic.
• Carbazole (C12H9N): It is a heterocyclic aromatic compound.
  • Coal Tar/Petrochemical Byproduct: Carbazole is primarily obtained from coal tar or as a byproduct of petroleum refining. Its price and availability are thus influenced by the steel industry (coke production) and the overall petrochemical market.
  • Niche Demand: Demand from other niche applications (e.g., dyes, plastics, electronics) can influence its market.
• Sodium Polysulfide (Na2Sx): It is a sulfur-containing inorganic compound.
  • Sulfur and Sodium Sulfide Markets: Sodium polysulfide is formed by reacting elemental sulfur with sodium sulfide. Its price is linked to global sulfur commodity markets and the chlor-alkali industry (for sodium hydroxide used to make sodium sulfide).
  • Hazardous Handling: Its corrosive and hazardous nature impacts storage and handling costs.
• Butanol (C4H10O): It is used as a reaction medium.
  • Petrochemical Market/Bio-based: Butanol is primarily produced from propylene (via hydroformylation to butyraldehyde, then hydrogenation) or through bio-fermentation. Its price is linked to crude oil/natural gas prices or biomass costs. Efficient solvent recovery and recycling are crucial to minimise manufacturing expenses.
     

Market Drivers for Indophenol

• Growing Demand for Analytical Testing (Ammonia Detection): The most significant market driver is the continuous and increasing demand for accurate and reliable methods for ammonia and ammonium ion detection. This is crucial in various sectors, including:
  • Environmental Monitoring: For monitoring water quality in wastewater treatment plants, natural water bodies, and industrial effluents globally.
  • Healthcare and Clinical Diagnostics: For determining ammonia levels in biological samples, relevant for kidney and liver function tests.
  • Food and Agriculture: For quality control in food processing and analysis of agricultural samples. The widespread adoption of spectrophotometric methods for ammonia detection directly fuels the demand for Indophenol as a key reagent.
• Niche Dye Applications: Its specific chromogenic properties maintain a consistent, albeit smaller, demand in specialised dye formulations (e.g., hair colouring, specific textile applications) where its unique blue shade is desired.
• Research and Development Activities: Continued R&D in chemical and biological sciences utilises Indophenol as a reagent for various assays, contributing to its sustained consumption.
• Quality Control in Industrial Processes: Indophenol finds use in various industrial quality control processes that require quick and accurate colourimetric detection of specific chemical parameters.
• Cost-Effectiveness as a Reagent: For specific analytical methods like the Berthelot reaction, Indophenol remains a cost-effective and well-established reagent, contributing to its consistent industrial procurement by laboratories and industries worldwide.
• Geo-locations: The demand for Indophenol is global, mirroring the distribution of industries reliant on chemical analysis, water treatment, and specialised dye manufacturing. Developed economies with advanced healthcare and environmental monitoring systems (North America, Europe) show consistent demand. Asia-Pacific is also a significant market due to its expanding industrial base and growing analytical testing needs.

Manufacturing Process of Indophenol

This report comprises a thorough value chain evaluation for Indophenol manufacturing and consists of an in-depth production cost analysis revolving around industrial Indophenol manufacturing.

The industrial production of Indophenol begins with a complex condensation reaction. The key feedstock materials involved in this process are p-nitrosophenol, carbazole, and sodium polysulfide, with butanol serving as the solvent and concentrated sulfuric acid (H2SO4) acting as the catalyst.

The synthesis begins with the controlled addition of an alkaline solution of p-nitrosophenol and carbazole to sodium polysulfide in butanol as the reaction medium. This mixture is then subjected to specific thermal conditions, with the reaction propagating in the presence of concentrated sulfuric acid (H2SO4). The reaction mixture is cooled to a low temperature, such as -20 degree Celsius, to initiate the condensation.

After this initial stage, the mixture is refluxed at a higher temperature, around 107 degree Celsius, and maintained for a prolonged period, such as 24 hours. This extended heating drives the condensation reaction, forming the chromogenic Indophenol molecule as the desired product. After the reaction, the product undergoes further purification steps, which may include filtration, washing, and drying, to obtain pure Indophenol.
