trans-Cinnamic acid(CAS: 140-10-3)

Trans-Cinnamic acid is an organic compound with the chemical formula C9H10O2. It is a naturally occurring aromatic carboxylic acid, commonly found in plants such as cinnamon. It has a melting point of around 134–136°C and is known for its characteristic aromatic odor and ability to form esters and other derivatives.

Trans-Cinnamic acid is widely used in the fragrance and flavor industries due to its pleasant aroma. It serves as a precursor in the synthesis of various pharmaceuticals, including drugs for diabetes and antihistamines. It is also used in research for its antioxidant and anti-inflammatory properties, and in the production of food additives and polymer materials.

Trans-Cinnamic acid is generally considered safe when used in appropriate amounts and under proper handling conditions. It has low toxicity and is not classified as a carcinogen. However, prolonged exposure or ingestion may cause skin irritation. Safety data sheets (SDS) should be consulted for detailed handling and exposure guidelines.

Trans-Cinnamic acid should be stored in a cool, dry, and well-ventilated place, away from direct sunlight and sources of heat. It is stable under normal storage conditions but should be kept in a sealed container to prevent moisture absorption and contamination. Proper labeling and storage according to safety regulations are essential.
