Quality Control

Our Ethanone, 1-[2-(Difluoromethoxy)-5-Methylphenyl]- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, impurity profiles, and physical characteristics are provided and available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or amber glass until use.
