Quality Control

Our 2-Thiophenethiol,5-Amino-(9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should be opened only under an inert environment and resealed immediately after use.
