Properties: Needles from ethanol, mp 243°. Soly in water at 15°: 0.12 g/100 ml, at 30°: 0.30 g/100 ml. More sol in hot water (about 1:60). Aq solns are neutral to litmus. Soly in urine at 37°: 360 mg/100 ml at pH 5.5 to 1100 mg/100 ml at pH 7.5. Slightly sol in alcohol, acetone. Practically insol in benzene, ether, chloroform. Freely sol in dil HCl and NaOH. Compared with sulfanilamide it is but slightly acetylated in the body. Do not confuse with sulfamethazine.
Melting point: mp 243°
