Product Name:trans-Cinnamic acid
English Name:trans-Cinnamic acid
CAS No.:140-10-3
Aliases:Cinnamic acid, Phenylacrylic acid, Benzalacetic acid, beta-Phenylacrylic acid, 3-Phenyl-2-propenoic acid
Molecular Formula:C9H8O2
Physical Properties:White to pale yellow powder with a cinnamon-like odor. Density 1.245 g/cm³, melting point 133°C, boiling point 300°C, flash point approximately 100°C. Slightly soluble in water (1 g dissolves in about 2 L of water at 25°C); soluble in hot water, ethanol, diethyl ether, acetone, glacial acetic acid, carbon disulfide, and other solvents. Rat oral LD50: 2500 mg/kg.
Uses:trans-Cinnamic acid is an important organic synthesis intermediate widely used in flavors and fragrances, food additives, daily chemicals, and agrochemicals. In flavors and fragrances, it serves as a fixative and blending material for formulating apple, cherry, fruity, and floral fragrances. Due to its inhibitory effect on tyrosinase, it is used in sunscreen cosmetic products. In the food industry, it acts as a preservative to extend the shelf life of grains, vegetables, and fruits. In organic synthesis, it is used as a heat stabilizer for PVC, a corrosion inhibitor for galvanized steel, a crosslinking agent for polyurethanes, and a raw material for photosensitive resins.
