Methyl butyrate
Methyl butyrate (CAS: 623-42-7), a clear, colourless liquid with the molecular formula C5H10O2 and a molecular weight of 102.13 g/mol, is a versatile organic ester. It possesses a characteristic fruity aroma and finds application as a solvent and in the synthesis of various chemical compounds. Its solubility in organic solvents and moderate reactivity make it a useful intermediate in organic chemistry.
Solvent Applications
Methyl butyrate serves as a solvent for various organic compounds due to its ester functionality and moderate polarity. It is miscible with common organic solvents like alcohol and diethyl ether, making it suitable for reactions and formulations requiring dissolution of organic materials.
Chemical Synthesis Intermediate
As a C5 ester, methyl butyrate is a valuable building block in organic synthesis. It can participate in esterification, transesterification, and other reactions to form more complex molecules used in pharmaceuticals, agrochemicals, and materials science.
Fragrance and Flavor Component
Due to its fruity aroma, methyl butyrate is sometimes utilised in the flavour and fragrance industry. Its presence can contribute to the characteristic scent profiles of various products, though this application is subject to specific regulatory approvals.
