Quality Control

Our 2-Chloro-5-Hydroxybenzaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and spectroscopic identification (IR, NMR), to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

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 store under an inert atmosphere for long-term preservation. Keep away from heat, sparks, and open flame.
