FAQ

What are the physical and chemical properties of 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.

How is Aminomethanesulfonic acid (CAS: 13881-91-9) typically synthesized?

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.

What industries use Aminomethanesulfonic acid (CAS: 13881-91-9)?

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.

What precautions should be taken when handling Aminomethanesulfonic acid (CAS: 13881-91-9)?

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).
