Quality Control

Our 4-Cyclopentyl-5-Methyl-4H-1,2,4-Triazole-3-Thiol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be kept sealed under an inert gas blanket after opening and protected from prolonged exposure to air and moisture.
