Quality Control

Our 4,4-Diethoxy-2-Butyn-1-Al is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at 2-8°C to maximize stability. Keep away from strong acids and oxidizing agents. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
