Product Description

Sulphanillic Acid is a kind of white to off-white cystalline. It's hydrate loses moisture
at 100 ℃, and anhydrous carbide begins to decompose at 280 ℃.
Sulphanillic Acid slightly soluble in cold water, insoluble in ethanol, ether and benzene,
soluble in sodium hydroxide solution and sodium carbonate solution.
Sulphanillic Acid has a very significant acidity.

Sulphanillic Acid


White crystal


≥ 99%

Content of aniline

≤ 0.02%

Insoluble substance in water


Dissolved state in aqueous sodium carbonate



It is white powder and turns into white crystal when it absorbs water in the air and attaches one molcular of crystal water. The crystal water will be lost when the temperature reaches 100℃. The density is 1.485(25℃/4℃), slightly soluble in cold water, benzene, ethanol and ether, and the melting point is 288℃ and decomposes at 300℃. 



TRANSPORTATION: Avoide crash and rain.


STORAGE: Should be stored in dry and ventilate place, and avoide moisture and deterioration.
