Chemical Structure

1,5-Dihydro-2H-pyrrolo[2,3-b]pyrazin-2-one CAS 1823364-07-3 chemical structure

Description

CATO supplies 1,5-Dihydro-2H-pyrrolo[2,3-b]pyrazin-2-one (CAS 1823364-07-3), a certified reference material (molecular formula C6H5N3O, MW 135.12 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H5N3O, 1,5-Dihydro-2H-pyrrolo[2,3-b]pyrazin-2-one contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 135.12 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.
