2-Methylpropanoic acid(CAS: 79-31-2)

2-Methylpropanoic acid (CAS: 79-31-2) is a colorless oily liquid with a pungent odor. It has a molecular weight of 90.08 g/mol and a boiling point of 144-145°C. The compound is slightly soluble in water but miscible with most organic solvents. It is acidic and can react with bases to form salts. It is also prone to esterification and can undergo various substitution reactions.

2-Methylpropanoic acid can be synthesized via several methods. One common method involves the hydration of propionaldehyde using a catalyst such as phosphoric acid. Another method includes the oxidation of 2-methylpropan-2-ol with sodium hypochlorite. Both methods yield high selectivity and good yields.

2-Methylpropanoic acid is widely used in the pharmaceutical industry as a precursor for the synthesis of esters and salts used in drug formulations. It is also utilized in the chemical industry for the production of polymers, particularly in the synthesis of polyurethanes. Additionally, it finds applications in the manufacturing of environmental sensing devices and as a raw material in semiconductor processes.

When handling 2-Methylpropanoic acid (CAS: 79-31-2), proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. It should be stored in a cool, dry place away from direct sunlight. In case of a spill, it should be handled with a fume hood to avoid inhalation. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency response procedures.
