Chemical Structure

1H-Pyrazole, 1-[[2-(difluoromethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- CAS 1604036-94-3 chemical structure

Description

1H-Pyrazole, 1-[[2-(difluoromethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- (CAS 1604036-94-3) is a high-purity analytical reference standard with the molecular formula C17H21BF2N2O3 and a molecular weight of 350.17 g/mol.

Structurally, 1H-Pyrazole, 1-[[2-(difluoromethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- (C17H21BF2N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 350.17 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1H-Pyrazole, 1-[[2-(difluoromethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
