Details:

Product name                 Sulfadiazine
CAS No.                            68-35-9
EINECS                             200-685-8
M.F.                                   C10H10N4O2S
M.W.                                      250.28

Properties
It is White or white-like crystal or powder and is odorless and tasteless. It gradually becomes dark upon exposure to light. It is insoluble in water, soluble in boiling water (1:60), slightly soluble in ethanol and acetone and insoluble in chloroform and ether. It is easily soluble in dilute hydrochloric acid, sodium hydroxide solution or ammonia solution. Its melting point is 252 ~ 256 ℃ (decomposition occurs at the same time). Its sodium salt is a white crystalline powder and is odorless with slightly bitter taste. Its sodium salt gradually turns to brown color up exposure to light. When being subject to long-term storage in the moist air, it can slowly absorb carbon dioxide and precipitate out sulfadiazine. It is soluble in water, slightly soluble in ethanol, but insoluble in chloroform and ether. Its 10% aqueous solution has a pH of 9.5 to 10.5.
