α-methylcinnamic acid(CAS: 1199-77-5)

α-Methylcinnamic acid (CAS: 1199-77-5) is a white crystalline solid with a molecular weight of 146.16 g/mol. It is slightly soluble in water and more soluble in organic solvents like ethanol and acetone. Chemically, it is reactive towards bases and can undergo esterification and amide formation. It has a melting point of about 110-112°C and a boiling point of around 260°C. It is an important intermediate in the synthesis of various pharmaceuticals and perfumery compounds.

α-Methylcinnamic acid is typically synthesized by the reduction of cinnamic acid with sodium borohydride or lithium aluminum hydride. Another method involves the amide hydrolysis of α-methylcinnamic anhydride. The yield is typically around 70-80%, and the reaction is performed under anhydrous conditions to avoid side reactions. This compound is also used as an intermediate in the synthesis of fragrances and pharmaceuticals.

α-Methylcinnamic acid (CAS: 1199-77-5) is widely used in the pharmaceutical industry for the synthesis of drugs, particularly those containing cinnamic acid derivatives. It is also used in the perfume industry as a precursor to fragrances. Additionally, it has applications in the polymer industry for the production of certain plastics and in the chemical industry for various intermediates and derivatization reactions.

When handling α-methylcinnamic acid (CAS: 1199-77-5), it is important to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. It should be stored in a dry, cool place, away from heat and oxidizing agents. Spills should be handled using appropriate absorbent materials and disposed of according to local regulations. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and procedures.
