Quality Control

Our Chloro-2-Methyl-Butene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and strong acid/organic solvent nature, it should be kept separate from strong oxidizers, bases, and reactive metals. Recommended storage temperature is 2-8°C (36-46°F) to maximize stability.
