Quality Control

Our production of Cyclopropanecarboxaldehyde, 3-Acetyl-2,2-Dimethyl-, (1R-Cis)- (9Ci) adheres to stringent internal quality standards to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is characterized by advanced analytical techniques including chiral HPLC, GC, and NMR to confirm identity, purity, and isomeric composition. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
