Quality Control

Our Cyclopropanecarboxaldehyde, 2-[(Acetyloxy)Methyl]-, (1R,2S)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with exacting research and production standards. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee identity, purity, and enantiomeric excess.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This material is easily oxidized and light-sensitive; allow the sealed container to reach ambient temperature before opening to minimize moisture ingress and degradation.
