Quality Control

Our 2-Aminobenzenethiol is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including HPLC, GC, and NMR for identity confirmation and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific tests is provided with each 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, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents, acids, and bases.
