4-(Aminomethyl)benzenesulfonic acid

Description:
4-(Aminomethyl)benzenesulfonic acid, also known as p-aminobenzenesulfonic acid, is an organic compound characterized by the presence of both an amino group and a sulfonic acid group attached to a benzene ring. This compound typically appears as a white to light yellow crystalline solid and is soluble in water due to the polar nature of its functional groups. It has a molecular formula that reflects its structure, containing a benzene ring substituted with an amino group (-NH2) and a sulfonic acid group (-SO3H) at the para position. The presence of these functional groups imparts acidic properties, making it a weak acid. It is commonly used in various applications, including as a reagent in organic synthesis, in the production of dyes, and as an intermediate in pharmaceuticals. Additionally, it can act as a pH indicator and is utilized in analytical chemistry. Safety precautions should be observed when handling this compound, as it may cause irritation to the skin and eyes.
