Chemical Structure
Description
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.
CATO supplies 5-Fluoro-6-(hydroxymethyl)-3-methyl-1,3-dihydro-2,1-benzoxaborol-1-ol (CAS 947168-20-9), a certified reference material (molecular formula C9H10BFO3, MW 195.98 g/mol) for analytical method development and quality control.
The molecular framework of 5-Fluoro-6-(hydroxymethyl)-3-methyl-1,3-dihydro-2,1-benzoxaborol-1-ol (C9H10BFO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
