(Z)-1,4-Dimethoxy-3-(4-(2-methyl-1,3-dioxolan-2-yl)pyridin-1-ium-1-yl)-1,4-dioxobut-2-ene-2-thiolate CAS 2492356-23-5 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 (Z)-1,4-Dimethoxy-3-(4-(2-methyl-1,3-dioxolan-2-yl)pyridin-1-ium-1-yl)-1,4-dioxobut-2-ene-2-thiolate.

CATO supplies (Z)-1,4-Dimethoxy-3-(4-(2-methyl-1,3-dioxolan-2-yl)pyridin-1-ium-1-yl)-1,4-dioxobut-2-ene-2-thiolate (CAS 2492356-23-5), a certified reference material (molecular formula C15H17NO6S, MW 339.36 g/mol) for analytical method development and quality control.

Structurally, (Z)-1,4-Dimethoxy-3-(4-(2-methyl-1,3-dioxolan-2-yl)pyridin-1-ium-1-yl)-1,4-dioxobut-2-ene-2-thiolate (C15H17NO6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 339.36 g/mol, it falls into the moderately-high-molecular-weight range. 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.
