4-Methylphenyl 2-methylpropanoate

Description:
4-Methylphenyl 2-methylpropanoate, also known as p-tolyl isobutyrate, is an organic compound characterized by its ester functional group. It is derived from the reaction of 4-methylphenol and isobutyric acid. This compound typically appears as a colorless to pale yellow liquid with a pleasant, fruity odor. It is moderately soluble in organic solvents but has limited solubility in water due to its hydrophobic nature. The molecular structure features a 4-methylphenyl group attached to an isobutyrate moiety, contributing to its aromatic characteristics. 4-Methylphenyl 2-methylpropanoate is often used in the fragrance and flavor industry, as well as in the synthesis of other chemical compounds. Its properties include a relatively low boiling point and a moderate vapor pressure, making it volatile under certain conditions. Safety data indicates that it should be handled with care, as it may cause irritation upon contact with skin or eyes. Proper storage and handling protocols are essential to ensure safety and stability.
