CAS 2373-76-4: 2-Methylcinnamic acid

Description: 2-Methylcinnamic acid is an organic compound characterized by its aromatic structure and carboxylic acid functional group. It is a derivative of cinnamic acid, featuring a methyl group at the second position of the phenyl ring. This compound typically appears as a white to pale yellow crystalline solid and is known for its pleasant floral scent, making it useful in the fragrance industry. Its molecular formula is C10H10O2, and it has a melting point that varies depending on purity and specific conditions. 2-Methylcinnamic acid is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic aromatic structure. It exhibits properties typical of carboxylic acids, including the ability to form hydrogen bonds and participate in acid-base reactions. Additionally, it can undergo various chemical transformations, such as esterification and reduction, making it a versatile intermediate in organic synthesis. Its applications extend beyond fragrances to include potential uses in pharmaceuticals and as a building block in organic chemistry.
