Quality Control

Our 3-Cyclopentene-1-Carboxaldehyde, 1-(Thioxomethyl)- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment. We support custom synthesis and can tailor purity grades to meet specific research or pilot-scale requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry, well-ventilated place. Due to its sensitivity to oxidation, the container should be kept sealed under positive pressure of inert gas after opening. Keep away from heat, sparks, and open flame.
