Quality Control

Our 4-Pentene-2-Ol99% is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR analysis, to ensure it meets the declared purity of 99% (GC area%) minimum and conforms to agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and at temperatures between 2°C and 8°C for long-term stability. Keep away from strong oxidizing agents and acids.
