Quality Control

Our production of 1-(2-Propen-1-Yl)-4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-1H-Pyrazole adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot is characterized by NMR (1H, 13C, 11B), HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profile is provided with every shipment.

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). This material is moisture-sensitive; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis of the boronate ester.
