Chemical Structure
Description
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.
{4-[(2-oxo-1,2-dihydropyridin-1-yl)methyl]phenyl}boronic acid (CAS 1334172-77-8), molecular formula C12H12BNO3 and molecular weight 229.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of {4-[(2-oxo-1,2-dihydropyridin-1-yl)methyl]phenyl}boronic acid (C12H12BNO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
