Quality Control

Our 1,3-Dithiolane-2-Carbonyl Chloride, 4-Methyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and FTIR, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C (refrigerated) or as specified on the label. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
