Quality Control

Our Raft Dithiobenzoate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for demanding polymerization applications. Each lot undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to verify identity, potency, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and degradation. Keep away from heat, sparks, and open flame. The container must be kept tightly sealed in a dry environment to minimize exposure to moisture.
