Quality Control

Our 3-Mercaptopicolinic Acid Hydrochloride is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurities, and other critical parameters are provided and available upon request, supporting compliance with cGMP and other relevant regulatory frameworks for advanced intermediates.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture uptake and oxidation.
