Quality Control

Our 4-Chloro-2,3-Dimethylbenzaldehyde is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency meet the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with each shipment.

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 light and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
