What Is Sodium p-styrenesulfonate

White to light yellow crystalline powder. The relative molecular mass is 206.19. The relative density is 0.5 (25°C). The melting point is 330°C (decomposition). Insoluble in benzene, acetone, carbon tetrachloride, soluble in water (22.2 at 20°C), methanol (5.0 at 20°C) Chemicalbook, dimethylformamide (8.5 at 20°C). This product has a vinyl group, coupled with the inductive effect of the para-sulfonic acid group, it has strong reactivity and polymerization ability, so it can be used as a vinyl monomer with a sulfonic acid group. Oral LD5016000mg/kg for male mice.
