Propyl cinnamate(CAS: 7778-83-8)

Propyl cinnamate (CAS: 7778-83-8) is a colorless to light yellow liquid with a distinctive aroma. The molecular weight is approximately 170.23 g/mol. It has a solubility of up to 1.5% in water and is soluble in common organic solvents such as ethanol and acetone. Propyl cinnamate is relatively stable under normal conditions but can react with strong acids or bases to form acetoacetic esters and other derivatives.

Propyl cinnamate (CAS: 7778-83-8) is typically synthesized by the reaction of cinnamic acid with propyl alcohol in the presence of a strong acid catalyst, such as sulfuric acid. The reaction is carried out at room temperature and yields a mixture of isomers, with the major isomer being the E-configuration. The yield is generally over 90%, and the product can be purified by recrystallization or distillation.

Propyl cinnamate (CAS: 7778-83-8) is widely used in the fragrance industry as a flavor and fragrance component. It is also utilized in the pharmaceutical industry as a solvent and in the formulation of topical medications. In the polymer industry, it serves as a plasticizer and antioxidant. Additionally, it is used in the food industry as a flavor enhancer and in the cosmetic industry as a fragrance ingredient and skin care additive.

When handling Propyl cinnamate (CAS: 7778-83-8), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be carried out in a well-ventilated fume hood to minimize exposure. Spills should be handled with care, using appropriate absorbent materials, and the area should be cleaned thoroughly. Always refer to the Safety Data Sheet (SDS) for detailed information on safe handling and disposal procedures.
