Imidodicarbonic acid, 2-(5-bromo-2-pyridinyl)-, 1,3-bis(1,1-dimethylethyl) ester CAS 209959-28-4

Description

Imidodicarbonic acid, 2-(5-bromo-2-pyridinyl)-, 1,3-bis(1,1-dimethylethyl) ester (CAS 209959-28-4), molecular formula C15H21BrN2O4 and molecular weight 373.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Imidodicarbonic acid, 2-(5-bromo-2-pyridinyl)-, 1,3-bis(1,1-dimethylethyl) ester (C15H21BrN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
