Quality Control

Our production of Cyclopropanecarbonyl Chloride, 3-(1Z)-1-Butenyl-2,2-Dimethyl-, (1R,3R)- (9Ci) adheres to stringent quality protocols to ensure the high purity and stereochemical integrity required for sensitive synthetic applications. Each batch is fully characterized using advanced analytical techniques including chiral HPLC, NMR, and GC-MS. Certificates of Analysis (COA) documenting identity, purity, enantiomeric excess, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
