Description

D-Glucitol 1,6-Bis(3-Mercaptopropionate) is a high-purity, multi-functional thiol compound derived from sorbitol. This specialty chemical is valued for its ability to act as a chain transfer agent and crosslinking modifier in advanced polymer synthesis, enabling precise control over molecular weight and network structure. It is essential for R&D and production teams in the polymer, adhesive, and advanced materials sectors seeking to enhance product performance and develop novel formulations.

Application

• Polymer Modification: Serves as a key chain transfer agent (CTA) in free-radical polymerization to control molecular weight and polydispersity.
• Thiol-Ene Chemistry: Acts as a versatile crosslinker or building block in UV-curable thiol-ene systems for coatings, adhesives, and optical resins.
• Advanced Material Synthesis: Used in the production of specialty polymers with tailored properties, such as improved flexibility, adhesion, or refractive index.
• Biomedical Polymers: Employed in the synthesis of degradable or biocompatible polymer networks for controlled drug delivery or tissue engineering scaffolds.
• Adhesive Formulations: Functions as a crosslinking co-agent to enhance the cure speed, strength, and thermal stability of epoxy and acrylic-based adhesives.
• Optical Materials: Utilized in the manufacture of high-refractive-index polymers and optical lenses due to its sulfur content and reactivity.

Quality Control

Our D-Glucitol 1,6-Bis(3-Mercaptopropionate) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and assay, titration for thiol content, and spectroscopic identification (IR, NMR), to ensure it meets precise specifications for advanced applications. A detailed 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, well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, open flames, and strong oxidizing agents. Due to its moisture-sensitive nature, the container must be kept tightly sealed after each use.
