1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium methanesulfonate CAS 155862-97-8 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 1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium methanesulfonate.

1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium methanesulfonate (CAS 155862-97-8) is a high-purity analytical reference standard with the molecular formula C21H18N3O4CH3O3S and a molecular weight of 471.48 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium methanesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 471.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium methanesulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
