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 3-[(2-oxo-2,3-dihydro-1H-indol-1-yl)methyl]furan-2-carboxylic acid (CAS 1097140-95-8), a certified reference material (molecular formula C14H11NO4, MW 257.24 g/mol) for analytical method development and quality control.
The molecular framework of 3-[(2-oxo-2,3-dihydro-1H-indol-1-yl)methyl]furan-2-carboxylic acid (C14H11NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
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.
