Quality Control

Our 4-Vinylbenzeneacetic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, guaranteeing traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
