Quality Control

Our production of 2-Chloro-5-Fluoro-3,4-Pyridinediamine adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (HPLC, GC, NMR) against established internal specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, 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, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
