Pentanoic anhydride(CAS: 2082-59-9)

Pentanoic anhydride (CAS: 2082-59-9) is a crystalline solid with a molecular weight of approximately 112.13 g/mol. It is poorly soluble in water but soluble in organic solvents. Chemically, it is highly reactive and can undergo condensation reactions easily.

Pentanoic anhydride can be synthesized by heating pentanoic acid in the presence of a dehydrating agent like phosphorus oxychloride or phosphorus pentoxide. The reaction is exothermic and results in the formation of the anhydride with high yield.

Pentanoic anhydride is used in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry as a monomer, and in the chemical sensors industry as a reagent. It is also utilized in the semiconductor industry for specific processing steps.

When handling pentanoic anhydride (CAS: 2082-59-9), it is essential to wear 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. Spills should be cleaned up immediately, and proper safety data sheets (SDS) should be consulted for detailed information on emergency procedures.
