Quality Control

Our p-Isopropylstyrene is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) with lot-specific data is provided with each shipment, confirming compliance with agreed specifications.

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.
