Quality Control

Our 1,4-Phenylenediacryloyl Chloride (Tech) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets the specifications required for technical and industrial applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and oxidizing agents.
