Quality Control

Every batch of Cyclobutanecarboxaldehyde, 1-(1-Oxopropyl)- (9Ci) is produced and tested under a strict quality management system. Our products undergo rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency for research and development applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and meet the exacting standards of our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
