Quality Control

Every batch of Cyclopropanecarboxylic Acid, 2-(3-Oxobutyl)-, (1R,2S)- (9Ci) is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, and chiral analysis to ensure high chemical and enantiomeric purity consistent with R&D and cGMP-grade material standards. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
