4-Methyloctanoic acid (CAS 54947-74-9)

4-Methyloctanoic acid, with the CAS number 54947-74-9, is a branched-chain fatty acid notable for its unique structural characteristics that influence its physical and chemical properties. This organic compound features a methyl group attached to the fourth carbon of an octanoic acid backbone, distinguishing it from straight-chain fatty acids. In research contexts, 4-Methyloctanoic acid is particularly valued for studies focused on the synthesis and behavior of branched-chain fatty acids, as well as their interactions within organic systems. Its branched structure impacts its melting and boiling points, making it a subject of interest in studies related to the phase behavior of fatty acids. Additionally, this compound has been used to explore the kinetics and mechanism of enzymatic reactions involving branched-chain fatty acids, especially those catalyzed by lipases and esterases. These enzymes often show different activity profiles depending on the molecular structure of the substrate, thus providing insights into enzyme specificity and function. Furthermore, 4-Methyloctanoic acid serves as a precursor in the synthesis of more complex branched-chain esters and derivatives, which are explored in the development of flavorings, fragrances, and other industrially relevant chemicals. Its application extends to the field of green chemistry, where it is used to develop sustainable synthetic pathways for producing industrially important chemicals with enhanced performance and reduced environmental impact.
