Description

Compared with other compounds in its class, the molecular weight of 276.24 g/mol gives 2-{2',5'-dioxo-2,3-dihydrospiro[1-benzopyran-4,4'-imidazolidine]-1'-yl}acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-{2',5'-dioxo-2,3-dihydrospiro[1-benzopyran-4,4'-imidazolidine]-1'-yl}acetic acid (CAS 851170-89-3), a certified reference material (molecular formula C13H12N2O5, MW 276.24 g/mol) for analytical method development and quality control.

The molecular framework of 2-{2',5'-dioxo-2,3-dihydrospiro[1-benzopyran-4,4'-imidazolidine]-1'-yl}acetic acid (C13H12N2O5) 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. 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.

CATO manufactures 2-{2',5'-dioxo-2,3-dihydrospiro[1-benzopyran-4,4'-imidazolidine]-1'-yl}acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
