The global DASDA market is fueled by rising demand for optical brighteners in emerging regions, as well as growing demand for DASDA in paper, fabrics, and detergents and soaps. High fluorescence, light fastness, heat resistance, and chemical stability are all characteristics of optical brighteners. As a result, by the fourth quarter of 2021, they were widely used in the paper and textile industries. Caustic soda is one of the key raw materials used in the manufacturing of this chemical. In November, liquid raw material caustic soda (50 percent) prices in the United States reached 550 USD/MT FOB Texas, before progressively declining in December to 510 USD/MT.

DASDA (4-4 di-amino stilbin 2-2 disulphonic acid) is basically a light-yellow coloured powder/cream, that is utilised in synthesis of dye stuffs, like optical brightening agents, fluorescent brightening agents, etc. It primarily functions as a chemical intermediate for manufacturing optical brightening agent.
Chemical Formula of DASDA:
While producing DASDA from sodium salt, sodium salt of para-nitrotoluene-orhto-sulphonate is often utilised. It is boiled in water with caustic soda and is finally reduced using zinc to produce DASDA.
