CAS 140-10-3

trans-Cinnamic acid

Description:

Trans-cinnamic acid is an organic compound characterized by its aromatic structure and is classified as a phenolic acid. It is a colorless to pale yellow solid at room temperature, with a characteristic sweet, balsamic odor. The compound is known for its trans configuration, where the phenyl and carboxylic acid groups are on opposite sides of the double bond, contributing to its stability and reactivity. Trans-cinnamic acid is slightly soluble in water but readily dissolves in organic solvents such as ethanol and ether. It has a melting point that typically falls within a specific range, indicating its crystalline nature. This compound is primarily used in the synthesis of various flavoring agents, fragrances, and as a precursor in the production of other chemicals. Additionally, trans-cinnamic acid exhibits biological activities, including antimicrobial and anti-inflammatory properties, making it of interest in pharmaceutical research. Its CAS number, 140-10-3, is a unique identifier that facilitates its recognition in chemical databases and regulatory frameworks.
