3-Hydroxy-4-(4-isopropoxy-2-methylbenzoyl)-1-(2-methoxyethyl)-5-(pyridin-3-yl)-1H-pyrrol-2(5H)-one CAS 505079-87-8

Description

CATO supplies 3-Hydroxy-4-(4-isopropoxy-2-methylbenzoyl)-1-(2-methoxyethyl)-5-(pyridin-3-yl)-1H-pyrrol-2(5H)-one (CAS 505079-87-8), a certified reference material (molecular formula C23H26N2O5, MW 410.46 g/mol) for analytical method development and quality control.

The molecular framework of 3-Hydroxy-4-(4-isopropoxy-2-methylbenzoyl)-1-(2-methoxyethyl)-5-(pyridin-3-yl)-1H-pyrrol-2(5H)-one (C23H26N2O5) is characterized by a flavonoid core, 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. 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 3-Hydroxy-4-(4-isopropoxy-2-methylbenzoyl)-1-(2-methoxyethyl)-5-(pyridin-3-yl)-1H-pyrrol-2(5H)-one 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.
