Quality Control

Our D3-Methyl Benzoylformate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (¹H, ¹³C, and Deuterium), HPLC, and GC-MS, to confirm chemical identity, isotopic purity (D-enrichment >98 atom % D typically), and chemical purity (typically ≥97% by HPLC). Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific client or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible organic solvents. For long-term storage under inert atmosphere, please contact our technical team for specific recommendations.
