Description

Heptadecyl Mercaptan CAS NO 53193-22-9 is a high-purity, long-chain aliphatic thiol characterized by its specific reactivity as a sulfur-based nucleophile. This compound is a critical intermediate and functional additive in advanced material synthesis, where its ability to act as a chain transfer agent or surface modifier is highly valued. It is essential for manufacturers in the polymer, lubricant additive, and specialty chemical sectors seeking to fine-tune molecular weight or impart specific surface properties to their products.

Application

• As a chain transfer agent (CTA) in free-radical polymerization processes to control polymer molecular weight and architecture.
• As a key intermediate in the synthesis of lubricant oil additives, such as extreme pressure (EP) and anti-wear agents.
• As a surface-modifying agent for nanoparticles and inorganic fillers to improve dispersion and compatibility in polymer matrices.
• In the production of specialty surfactants and flotation agents for mineral processing.
• As a building block for organic synthesis, particularly in the creation of sulfur-containing ligands and pharmaceuticals.
• For the functionalization of gold surfaces and quantum dots in sensor and electronic material development.
