Chemical Structure

2-Methyl-3-(methylthio)-4-(pyridin-4-yl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridine-1,6(5H)-dione CAS 1269531-77-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-3-(methylthio)-4-(pyridin-4-yl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridine-1,6(5H)-dione.

2-Methyl-3-(methylthio)-4-(pyridin-4-yl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridine-1,6(5H)-dione (CAS 1269531-77-2) is a high-purity analytical reference standard with the molecular formula C14H13N3O2S and a molecular weight of 287.34 g/mol.

Based on its molecular formula C14H13N3O2S, 2-Methyl-3-(methylthio)-4-(pyridin-4-yl)-2,3-dihydro-1H-pyrrolo[3,4-c]pyridine-1,6(5H)-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 287.34 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.
