Quality Control

Our Benzaldehyde, 2,3-Diethynyl- (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We adhere to cGMP principles for manufacturing, ensuring reliability for research and scale-up activities.

Storage

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