CAS 2227-58-9: 3-(4-Methylphenyl)-2-propynoic acid

Description: 3-(4-Methylphenyl)-2-propynoic acid, also known by its CAS number 2227-58-9, is an organic compound characterized by its unique structure, which includes a propynoic acid moiety and a para-methylphenyl group. This compound features a triple bond between the second and third carbon atoms of the propynoic acid chain, contributing to its reactivity and potential applications in organic synthesis. It is typically a white to off-white solid at room temperature and is sparingly soluble in water, but more soluble in organic solvents such as ethanol and acetone. The presence of the methyl group on the phenyl ring enhances its hydrophobic character and can influence its biological activity. 3-(4-Methylphenyl)-2-propynoic acid may exhibit various chemical properties, including acidity due to the carboxylic acid functional group, and it can participate in reactions typical of alkynes, such as nucleophilic additions and cycloadditions. Its derivatives and related compounds are of interest in medicinal chemistry and materials science for their potential therapeutic and functional properties.
