4-((Trimethylsilyl)ethynyl)benzoic acid

Description:
4-((Trimethylsilyl)ethynyl)benzoic acid, with the CAS number 16116-80-6, is an organic compound characterized by the presence of a benzoic acid moiety substituted with a trimethylsilyl-ethynyl group at the para position. This compound typically exhibits a white to off-white solid appearance and is soluble in organic solvents such as dichloromethane and tetrahydrofuran, but may have limited solubility in water due to its hydrophobic trimethylsilyl group. The presence of the ethynyl group introduces alkyne characteristics, which can participate in various chemical reactions, including coupling reactions and cycloadditions. The trimethylsilyl group enhances the stability of the compound and can also serve as a protecting group for functional groups during synthetic transformations. Additionally, the carboxylic acid functional group allows for potential hydrogen bonding and reactivity in acid-base chemistry. Overall, this compound is of interest in organic synthesis and materials science, particularly in the development of functionalized polymers and advanced materials.
