Quality Control

Every batch of 4-Nitro-2-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Benzonitrile is manufactured and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR (¹H, ¹³C, ¹¹B), and GC-MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your regulatory and R&D requirements.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and when opening the container to prevent degradation.
