Quality Control

Our 3-Amino-5-Chlorophenol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC chromatograms and NMR spectra, to verify identity and purity. Certificates of Analysis (COA) are available for every batch and provided upon request, detailing compliance with agreed specifications.

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 or argon) for long-term preservation. Keep away from strong oxidizing agents and incompatible materials.
