Quality Control

Our cis-2-Buten-1-Ol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring high-purity intermediates under cGMP or ISO 9001 frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
