CAS 77758-51-1

5-Hexynoic acid, methylester

Description:

5-Hexynoic acid, methyl ester, also known by its CAS number 77758-51-1, is an organic compound characterized by its aliphatic structure featuring a terminal alkyne functional group. This compound is an ester derived from 5-hexynoic acid and methanol, resulting in a methyl ester form. It typically appears as a colorless to pale yellow liquid with a distinctive odor. The presence of the alkyne group imparts unique reactivity, making it useful in various organic synthesis applications, particularly in the formation of carbon-carbon bonds. Its molecular structure includes a six-carbon chain with a triple bond between the fifth and sixth carbon atoms, contributing to its unsaturation. 5-Hexynoic acid, methyl ester is soluble in organic solvents and exhibits moderate polarity. It is important to handle this compound with care, as it may pose health risks if inhaled or ingested. Overall, its unique properties make it a valuable intermediate in chemical synthesis and research.
