4-(4-Ethoxy-3-methylbenzoyl)-1-(3-ethoxypropyl)-3-hydroxy-5-(p-tolyl)-1H-pyrrol-2(5H)-one CAS 617694-22-1 chemical structure

Description

The occurrence of 4-(4-Ethoxy-3-methylbenzoyl)-1-(3-ethoxypropyl)-3-hydroxy-5-(p-tolyl)-1H-pyrrol-2(5H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(4-Ethoxy-3-methylbenzoyl)-1-(3-ethoxypropyl)-3-hydroxy-5-(p-tolyl)-1H-pyrrol-2(5H)-one (CAS 617694-22-1), a certified reference material (molecular formula C26H31NO5, MW 437.53 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-Ethoxy-3-methylbenzoyl)-1-(3-ethoxypropyl)-3-hydroxy-5-(p-tolyl)-1H-pyrrol-2(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
