Chemical Structure
Description
1,4-Dihydrofuro[3,4-b]pyrazine-2,3,5,7-tetraone (CAS 58084-26-7) is a high-purity analytical reference standard with the molecular formula C6H2N2O5 and a molecular weight of 182.09 g/mol.
The molecular framework of 1,4-Dihydrofuro[3,4-b]pyrazine-2,3,5,7-tetraone (C6H2N2O5) is characterized by a carbohydrate-derived structure, an amide group. 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.
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.
