Quality Control

Our 4,4,5,5-Tetramethyl-2-(4-Octylphenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and GC, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee batch-to-batch consistency and reliability for your critical synthesis workflows.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
