Quality Control

Our trans-4-Chloro-2-Pentene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure high chemical purity and isomeric integrity. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from strong acids and incompatible organic solvents. Due to its light-sensitive nature and reactivity, containers should be kept tightly sealed under an inert atmosphere when not in use to maintain product stability.
