Aniline 3 Sulfonic Acid also known as M Sulfanilic Acid is a high purity organic compound used extensively as an intermediate in the manufacture of dyes and pigments. It has the molecular formula C6H7NO3S and appears as a white to light brown crystalline powder. This compound is water soluble and features both an amino group and a sulfonic acid group which make it highly reactive for diazotization and coupling reactions. Aniline 3 Sulfonic Acid is a key raw material in the synthesis of azo dyes acid dyes and direct dyes due to its ability to provide strong chromophoric properties. It is also used in the production of pharmaceutical and agrochemical compounds. The material is thermally stable and maintains its integrity under standard industrial storage and handling conditions. It should be stored in a cool dry and well ventilated space in HDPE bags with inner liners to avoid contamination and moisture absorption.
