Quality Control

Our 4',6-Dichloroflavan is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided.
