Quality Control

Our production of 4-Cyclopentene-1,3-Diol, 1-Methyl-, 3-Acetate, (1S,3R)- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and high enantiomeric purity. Products undergo rigorous analytical testing, including chiral HPLC, NMR, and GC-MS, to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials such as strong oxidizing agents.
