Quality Control

Every batch of [1,1:3,1-Terphenyl]-4,6-Diol is manufactured under a cGMP-compliant quality management system. Our products undergo rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with stringent industry standards. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment and is available upon request.

Storage

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