Quality Control

Our Changweikang Aldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, confirming compliance with customer specifications and relevant industry standards for research and process chemistry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
