Quality Control

Our 4-Phenyl-1-Butene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for manufacturing and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and oxidizing agents.
