Quality Control

Our 5-Chloro-2-Methylthiophenol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including GC, HPLC, and NMR, to verify identity and quantify impurities. 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 in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or amber glass until use.
