1-(6-methoxypyridin-3-yl)-2,5-dihydro-1H-pyrrole-2,5-dione CAS 138949-31-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.18 g/mol gives 1-(6-methoxypyridin-3-yl)-2,5-dihydro-1H-pyrrole-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(6-methoxypyridin-3-yl)-2,5-dihydro-1H-pyrrole-2,5-dione (CAS 138949-31-2) is a high-purity analytical reference standard with the molecular formula C10H8N2O3 and a molecular weight of 204.18 g/mol.

The molecular framework of 1-(6-methoxypyridin-3-yl)-2,5-dihydro-1H-pyrrole-2,5-dione (C10H8N2O3) is characterized by an amino-acid-derived structure, 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. 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.
