Chemical Structure
Description
(2-(Difluoromethyl)pyrimidin-5-yl)boronic acid (CAS 2096341-52-3) is a high-purity analytical reference standard with the molecular formula C5H11BF2N2O2 and a molecular weight of 179.96 g/mol.
Structurally, (2-(Difluoromethyl)pyrimidin-5-yl)boronic acid (C5H11BF2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 179.96 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
