Quality Control

Our β,2-Dimethylstyrene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C to minimize polymerization and maintain stability. Keep away from strong oxidizing agents.
