Aminomethanesulfonic acid(CAS: 13881-91-9)

Aminomethanesulfonic acid is a white crystalline solid with a molecular weight of approximately 117.11 g/mol. It has a solubility of about 28.7 g/100 mL in water at 25°C. It is a weak acid and reacts with bases to form salts. It is not flammable but may react with strong oxidizers.

Aminomethanesulfonic acid can be synthesized by reacting methanesulfonyl chloride with ammonia. Commonly, this involves adding ammonia to a solution of methanesulfonyl chloride to form the acid. The process is carried out under anhydrous conditions and may require a catalyst such as triethylamine to enhance the reaction rate and yield.

Aminomethanesulfonic acid is used in various industries including pharmaceuticals, where it serves as a raw material for the synthesis of certain drugs. It is also used in the production of polymers, sensors, and as a pH adjuster in semiconductor manufacturing.

When handling Aminomethanesulfonic acid, it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The substance should be handled in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up using appropriate spill response procedures outlined in the Safety Data Sheet (SDS).
