Quality Control

Our 3-(1-Methoxy-1-Methylethoxy)Propyne is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its ether and alkyne functionality, it should be stored under an inert atmosphere (e.g., nitrogen or argon) if long-term stability is required, and kept separate from strong oxidizing agents.
