Quality Control

Our Ethanone, 1-(3,4-Diethynylphenyl)- (9Ci) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and FTIR, to verify identity, purity, and conformity to specifications. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring full traceability and compliance with your research or production requirements. For custom purity grades or specific impurity profiles, please contact our technical team.

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). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
