Quality Control

Our Benzaldehyde, 2-(2-Propynyl)- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters. Our quality system is designed to meet the stringent requirements of cGMP for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
