Quality Control

Our Benzeneacetaldehyde, 4-Hydroxy-2-Methyl- (9Ci) is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request 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 a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
