Pyrimethamine Production Cost Reports

The report provides a detailed analysis essential for establishing a pyrimethamine production plant. It encompasses all critical aspects necessary for pyrimethamine production, including the cost of pyrimethamine production, pyrimethamine plant cost, pyrimethamine production costs, and the overall pyrimethamine production plant cost. Additionally, the study covers specific expenditures associated with setting up and operating a pyrimethamine production plant. These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.

Pyrimethamine is a folic acid antagonist which is used to treat toxoplasmosis and cystoisosporiasis. It is used for preventing Pneumocystis jirovecii pneumonia in HIV/AIDS patients when combined with dapsone. It targets parasites by stopping dihydrofolate reductase and disrupting nucleic acid synthesis. It is used in combination with sulfadiazine and leucovorin for treating toxoplasmosis.  It is also utilised for ocular toxoplasmosis, actinomycosis, isosporiasis, and investigational roles in slowing Tay-Sachs disease progression or treating ALS via enhanced β-hexosaminidase activity. Its common side effects include nausea, vomiting, loss of appetite, headache, dizziness, diarrhoea, anaemia, leukopenia, thrombocytopenia, rash, and glossitis.

The market for pyrimethamine is influenced by the growing cases of toxoplasmosis and malaria. The rising immunocompromised populations and government and WHO initiatives for essential medicines contribute to its demand. The availability of low-cost generics and R&D into combination therapies or reformulations improves bioavailability and adherence. The industrial pyrimethamine procurement is affected by volatile pricing from past shortages, limited manufacturers leading to supply chain vulnerabilities, and regulatory hurdles for quality assurance. Also, reliance on institutional bulk buying by hospitals and programs, competition from alternatives like atovaquone, and regional disparities impact its sourcing strategies.

Raw Material for Pyrimethamine Production

According to the pyrimethamine production plant project report, the key raw materials used in the production of pyrimethamine include 4-chlorobenzyl cyanide, methyl propionate, sodium methoxide, ethyl orthoformate, and guanidine.

Production Process of Pyrimethamine

The extensive pyrimethamine production cost report consists of the following major industrial production process:

1. From 4-chlorobenzyl cyanide: The production process of Pyrimethamine starts with the condensation of 4-chlorobenzyl cyanide and methyl propionate. This takes place in the presence of sodium methoxide, forming a β-ketonitrile intermediate. This intermediate is then reacted with ethyl orthoformate to produce the corresponding methoxy methylene derivative. This is followed by the cyclocondensation of this activated intermediate with guanidine, which results in heterocyclization to form the pyrimidine ring system, giving pyrimethamine as the final product.

Pyrimethamine is a folic acid antagonist with the molecular formula C12H13ClN4 and molecular weight of 248.71 g/mol. It appears as a white to off-white crystalline powder with a melting point of 233-234 degrees Celsius and low water solubility. It has a density of around 1.22 g/cm³ and a boiling point of around 393 degrees Celsius. It has the flash point of 251 degrees Celsius with vapor pressure of 8.34×10^-10 mmHg at 25 degrees Celsius with a refractive index of 1.611. It is chemically structured as 5-(4-chlorophenyl)-6-ethylpyrimidine-2,4-diamine with a pKa around 7 and light-sensitive stability requiring dark, inert storage. All these physical and chemical properties support its formulation as an oral tablet for antimalarial and antiparasitic use.
