Sulfadiazine is an organic compound with a molecular formula of C10H10N4O2S, white or off-white crystals or powders, odorless, tasteless, and gradually darkened when exposed to light. Almost insoluble in water, soluble in boiling water (1:60), slightly soluble in ethanol and acetone, insoluble in chloroform and ether, soluble in dilute hydrochloric acid, sodium hydroxide solution or ammonia solution. Melting point 252~256 °C (simultaneous decomposition). Its sodium salt is white crystalline powder, odorless, slightly bitter taste. Gradient brownish upon light. Left in humid air for a long time, carbon dioxide is slowly absorbed and sulfadiazine is precipitated.
