Heptadecanoyl chloride (CAS 40480-10-2)

Heptadecanoyl chloride, a long-chain fatty acid chloride, plays a pivotal role in research focused on organic synthesis and surface modification. As an acylating agent, it is instrumental in creating heptadecanoate esters and amides, facilitating the attachment of a hydrophobic C17 chain to various substrates. This reactivity enables it to modify natural and synthetic polymers, enhancing their water resistance, thermal stability, and mechanical properties. For instance, in modifying cellulose and other biopolymers, heptadecanoyl chloride imparts significant hydrophobicity, making it valuable in studying the development of biodegradable coatings, adhesives, and packaging materials. Furthermore, in surface chemistry, heptadecanoyl chloride is crucial for creating self-assembled monolayers (SAMs) on metal and silicon substrates. Its long-chain structure forms densely packed films, which are vital for understanding surface interactions, wettability, and adhesion. These SAMs are used extensively in the study of anti-corrosive coatings, lubrication, and the modification of surface energy. In chemical synthesis, this compound is also utilized for developing fatty acid derivatives for studying lipid metabolism and the role of long-chain fatty acids in biological systems. Overall, its versatility in acylation and surface engineering provides a foundation for comprehensive studies in polymer science, materials research, and organic chemistry.
