Methyl butyrate (CAS 623-42-7)

Methyl butyrate, cataloged under CAS number 623-42-7, is a methyl ester of butyric acid, characterized by its fruity aroma reminiscent of apples or pineapples, making it popular in flavor and fragrance industries. Beyond its commercial applications, methyl butyrate is a valuable compound in scientific research, particularly in the study of organic synthesis and esterification processes. This ester serves as a model compound for investigating the kinetics and mechanisms of ester formation, a fundamental reaction in organic chemistry where an acid reacts with an alcohol, yielding an ester and water. Methyl butyrate′s relatively simple structure allows researchers to study esterification under various conditions without the complications presented by more complex molecules. In chemical synthesis, it provides insights into reaction conditions that optimize yield and selectivity for ester production. Furthermore, methyl butyrate is utilized in analytical chemistry as a standard for calibrating instruments designed to detect and measure volatile organic compounds. Its distinct and strong odor profile makes it ideal for studies in olfactory response and the development of synthetic aroma compounds. Additionally, its role in food chemistry research includes exploring the impact of esters on flavor profiles and stability, contributing to the development of new food products and enhancement of existing ones.
