Sulphanilic acid

Product Description

Sulfanilic acid (also spelled as sulphanilic acid) is a white crystalline powder with the chemical formula C6H7NO3S. It is a derivative of aniline, containing a sulfonic acid group (-SO3H) in the para position of the benzene ring. Sulfanilic acid is soluble in water and is commonly used in the chemical industry as an intermediate in the production of dyes and pigments. It is also used in analytical chemistry as a reagent for the detection and quantification of nitrite ions in water and food samples, and in the pharmaceutical industry as an intermediate for the synthesis of sulfa drugs. Sulfanilic acid is considered a relatively safe chemical, although it can be irritating to the skin, eyes, and respiratory tract upon contact or inhalation, and it should be handled with care and appropriate safety measures.
