Quality Control

Every batch of 3,4,5-Trichloro-2-Hydroxybenzoyl Chloride is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements for sensitive synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and oxidizing agents.
