Quality Control

Our 1-Chloro-1,2,3-Butanetriene is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Quality is verified through advanced analytical techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and reactive nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C (refrigerated) for extended stability. Keep away from strong acids, bases, and oxidizing agents.
