Quality Control

Our 4,5-Dichloro-2-Nitrobenzaldehyde is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity determination, to meet the stringent requirements of our global clientele. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage of bulk quantities. Keep away from heat, sparks, and open flame.
