Quality Control

Every batch of Cyclopropanecarboxaldehyde, 2-(Phenylmethyl)-, (1S,2S)- (9Ci) is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including chiral HPLC, to ensure high chemical and enantiomeric purity, identity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 place. Due to its sensitivity, the container should be kept tightly sealed after each use to minimize exposure to air and moisture.
