Quality Control

Our 4-Methyl-1,4-Hexadien is produced under a strict quality management system. Each batch is analyzed using advanced techniques including GC, GC-MS, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) when not in use to prevent polymerization or degradation. Recommended storage temperature is 2-8°C for long-term stability.
