Quality Control

Our [Isopropoxy(Thiocarbonyl)Thio]Acetic Acid Sodium Salt is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity, essential for reproducible polymerization results. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities that could inhibit polymerization. A comprehensive Certificate of Analysis (COA) detailing assay, purity by HPLC, and other relevant parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat and incompatible materials.
