Quality Control

Our p-Terphenyl, 4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)- is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards, and custom synthesis and purity grades (e.g., >97%, >98%, >99%) are available to meet specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for extended stability.
