Quality Control

Our 2,4-Dichloro-5-Methoxybenzaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity and purity against established specifications. Certificates of Analysis (COA) detailing all test results are 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, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
