Quality Control

Our 2-Butene-D8 is produced under stringent conditions to ensure exceptional isotopic and chemical purity. Each batch undergoes comprehensive analytical testing, including NMR, GC-MS, and IR spectroscopy, to verify identity, isotopic enrichment (typically >98 atom % D), and chemical purity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with your specified requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area, preferably under an inert atmosphere. Recommended storage temperature is 2-8°C to minimize loss and maintain stability. Keep away from heat, sparks, and open flames.
