Description

Hexadecyl Mercaptoacetate is a high-purity, long-chain alkyl ester of mercaptoacetic acid, valued for its role as a versatile intermediate and functional additive. Its molecular structure, featuring both a thiol and an ester group, makes it a critical component in synthesis and material modification processes. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to impart specific properties like adhesion, lubrication, or stabilization to their formulations.

Application

• As a key intermediate in the synthesis of specialized surfactants and emulsifiers.
• As a polymer modification agent and chain transfer agent in controlled radical polymerization.
• As an additive in lubricant and grease formulations to enhance extreme pressure (EP) and anti-wear properties.
• In the production of corrosion inhibitors and metal surface treatment agents.
• As a building block for synthesizing organosulfur compounds with specific biological or chemical activity.
• In the formulation of adhesion promoters for coatings and sealants.
• For research and development in novel material science applications.

Quality Control

Our Hexadecyl Mercaptoacetate is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong oxidizing agents.
