Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Furan-2-ylmethyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid.
CATO supplies 2-(Furan-2-ylmethyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid (CAS 356575-75-2), a certified reference material (molecular formula C14H9NO5, MW 271.22 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H9NO5, 2-(Furan-2-ylmethyl)-1,3-dioxo-2,3-dihydro-1H-isoindole-5-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
