Chemical Structure
Description
(2-Formyl-4-(trifluoromethyl)phenyl)boronic acid (CAS 1217501-35-3) is a high-purity analytical reference standard with the molecular formula C8H6BF3O3 and a molecular weight of 217.94 g/mol.
Structurally, (2-Formyl-4-(trifluoromethyl)phenyl)boronic acid (C8H6BF3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 217.94 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
