Heptadecanoic Acid, 17-Bromo-, Methyl Ester (CAS No. 72338-49-9)

Heptadecanoic acid, 17-bromo-, methyl ester is a compound with the CAS registry number 72338-49-9. This compound is a methyl ester derivative of 17-bromoheptadecanoic acid, which belongs to the family of fatty acids with a bromine substituent at the terminal position. The compound has a molecular formula of C₁₈H₃₅BrO₂, and its molecular weight is approximately 405.4 g/mol. The structure of this compound consists of a straight-chain alkyl group with 16 carbons, a carboxylic acid group at one end, and a bromine atom at the terminal position (C17), with the carboxylic acid converted into a methyl ester group.

The synthesis of heptadecanoic acid, 17-bromo-, methyl ester typically involves the bromination of heptadecanoic acid followed by esterification. Bromination can be achieved through various methods, such as free radical bromination or electrophilic substitution, depending on the desired regioselectivity and reaction conditions. The conversion to the methyl ester is usually carried out using methanol in the presence of an acid catalyst or through transesterification reactions.

CAS No. 72338-49-9 is known for its potential applications in various fields, including materials science and biotechnology. Recent studies have explored its use as a precursor for the synthesis of advanced materials, such as polyesters and polyamides, where the bromine substituent can serve as a functional group for further modifications. Additionally, this compound has been investigated for its role in bio-based polymers, contributing to the development of sustainable materials with tailored properties.

In terms of physical properties, heptadecanoic acid, 17-bromo-, methyl ester is typically a viscous liquid or solid at room temperature, depending on its exact structure and degree of unsaturation. It has a melting point around 50–60°C and is sparingly soluble in water but soluble in organic solvents such as dichloromethane and diethyl ether. The presence of the bromine atom imparts some degree of polarity to the molecule, which affects its solubility and reactivity.

The chemical stability of this compound is generally good under normal storage conditions; however, it may undergo hydrolysis in the presence of water and strong acids or bases. To ensure stability during storage and handling, it is recommended to keep it in an inert atmosphere and avoid exposure to strong oxidizing agents or light.
