2-Methylcinnamic acid is a valuable unsaturated aromatic acid intermediate with wide industrial usage. It is mainly applied in pharmaceutical synthesis to prepare anti-inflammatory, antibacterial and cardiovascular medicines via esterification and addition reactions. It acts as key raw material for synthesizing essence and flavor compounds, contributing unique aromatic notes to daily fragrance products. In agrochemical industry, it is used to manufacture plant growth regulators and fungicides. It also serves as cross-linking agent and modifier for resin and polymer materials to enhance material durability. Besides, it is used as organic synthetic building block for cyclic compounds and fine chemical derivatives. Its active double bond and carboxyl group enable diverse chemical conversions, occupying vital position in medicine, spice and new material industries.
