Quality Control

Our Cyclopentanone, 4,4-Dimethyl-2-(1-Methylethyl)- (9Ci) is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our quality system supports cGMP standards for pharmaceutical intermediates and caters to the stringent requirements of industrial and research customers globally.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
