Quality Control

Our 2-Butenedinitrile, 2,3-Bis[4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]- is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot is characterized by advanced analytical techniques including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

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 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.
