Quality Control

Our 2-Cyclopropylethynyl-Benzaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results. Our commitment to quality supports applications requiring high-purity intermediates for research and development.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation and light, prolonged exposure to air or light should be avoided. Keep away from heat and incompatible materials.
