Quality Control

Our 7-Chloro-4-Mercaptoquinoline-2-Carboxylic Acid Hcl is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption. Keep away from incompatible materials.
