Quality Control

Our 2,5-Dichloro-3-Methyl-1,4-Benzoquinone is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with every shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque or amber packaging during storage and handling.
