1-Cyclopropyl-1,3-butanedione(CAS: 21573-10-4)

1-Cyclopropyl-1,3-butanedione is a colorless or slightly yellow liquid with a molecular weight of 120.17 g/mol. It is soluble in ethanol and acetone but less soluble in water. It is reactive and undergoes easy dehydration and decarboxylation reactions.

1-Cyclopropyl-1,3-butanedione is typically synthesized through the condensation of cyclopropylmethyl acetate with formaldehyde using an acid catalyst. The reaction is highly selective and yields up to 90% of the desired product.

1-Cyclopropyl-1,3-butanedione is used in the pharmaceutical industry as a precursor for the synthesis of certain drugs. It also finds applications in the polymer industry for the development of specific polymers and in the chemical sensing industry as a sensing material.

When handling 1-Cyclopropyl-1,3-butanedione, protective gloves and safety goggles should be worn. It should be handled in a well-ventilated area or fume hood. Spills should be cleaned up with care, and appropriate personal protective equipment (PPE) should be used. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
