Description

Glyceryl 3-Mercaptopropionate is a versatile sulfur-containing ester derived from glycerol and 3-mercaptopropionic acid. This multifunctional compound is valued for its ability to act as a chain transfer agent, stabilizer, and reactive intermediate in advanced polymer synthesis. It is essential for manufacturers in the polymer, adhesive, and specialty chemical industries seeking to modify material properties such as viscosity, stability, and cross-linking density.

Application

• Polymer & Resin Modification: Serves as a crucial chain transfer agent (CTA) and cross-linking agent in the production of acrylic resins, polyurethanes, and other specialty polymers.
• Adhesive & Sealant Formulation: Imparts enhanced adhesion, flexibility, and curing characteristics to high-performance adhesives and sealants.
• Stabilizer & Antioxidant Precursor: Acts as an intermediate in the synthesis of antioxidants and stabilizers for plastics and rubber to prevent degradation.
• Pharmaceutical & Cosmetic Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and personal care additives where thiol functionality is required.
• Surface Coating Additive: Enhances the performance and durability of industrial coatings, paints, and inks.
• Chemical Intermediate: A key building block for further organic synthesis, including the production of other mercapto-functionalized compounds.

Quality Control

Our Glyceryl 3-Mercaptopropionate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay, purity, and impurity profile analysis via techniques such as HPLC and GC, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents, strong acids, and strong bases.
