2-Amino-N-methylbenzenesulfonamide(CAS: 16288-77-0)

2-Amino-N-methylbenzenesulfonamide is a white crystalline solid with a molecular weight of approximately 229.23 g/mol. It is poorly soluble in water but soluble in organic solvents. Chemically, it is relatively stable but can react with strong acids or bases. It has a pKa of around 7.5 and is used in various chemical reactions due to its amine and sulfonamide functionalities.

2-Amino-N-methylbenzenesulfonamide is typically synthesized through the reaction of N-methylbenzenesulfonamide with ammonia. The reaction is carried out under mild conditions, and a mild acid catalyst such as hydrochloric acid is often used to promote the amide formation. The yield is generally high, and the product can be purified by recrystallization.

2-Amino-N-methylbenzenesulfonamide is used in industries such as pharmaceuticals, where it serves as an intermediate in the synthesis of drugs. It is also used in polymer science for the modification of polymers and in the development of sensors and semiconductors due to its functional groups.

When handling 2-Amino-N-methylbenzenesulfonamide, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a fume hood to minimize exposure. Spills should be cleaned up carefully, and the substance should be stored in a cool, dry place away from strong acids and bases. Safety data sheets (SDS) should always be consulted for detailed handling and storage information.
