(Z)-3-(4-Methoxypyridin-1-ium-1-yl)-1,4-dioxo-1,4-diphenylbut-2-ene-2-thiolate CAS 2377723-52-7

Description

As a certified reference material (CRM), (Z)-3-(4-Methoxypyridin-1-ium-1-yl)-1,4-dioxo-1,4-diphenylbut-2-ene-2-thiolate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(Z)-3-(4-Methoxypyridin-1-ium-1-yl)-1,4-dioxo-1,4-diphenylbut-2-ene-2-thiolate (CAS 2377723-52-7) is a high-purity analytical reference standard with the molecular formula C22H17NO3S and a molecular weight of 375.44 g/mol.

The molecular framework of (Z)-3-(4-Methoxypyridin-1-ium-1-yl)-1,4-dioxo-1,4-diphenylbut-2-ene-2-thiolate (C22H17NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
