2-Amino-4-chloro-5-methylbenzenesulfonic acid

Description:

2-Amino-4-chloro-5-methylbenzenesulfonic acid, also known as sulfanilic acid, is an aromatic sulfonic acid characterized by its amino group (-NH2), a chloro substituent, and a methyl group on a benzene ring. This compound is typically a white to pale yellow crystalline solid that is soluble in water, reflecting its polar sulfonic acid functional group. It has a melting point that varies depending on purity and form, but it generally exists as a stable solid under standard conditions. The presence of the sulfonic acid group imparts acidic properties, allowing it to participate in various chemical reactions, including sulfonation and diazotization. It is commonly used in the synthesis of dyes, pharmaceuticals, and as a reagent in analytical chemistry. Additionally, it can act as a pH indicator due to its ability to change color in response to pH variations. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
