4-(4-Fluorophenyl)-N-phenethyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide CAS 1291852-87-3

Description

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.

CATO supplies 4-(4-Fluorophenyl)-N-phenethyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide (CAS 1291852-87-3), a certified reference material (molecular formula C23H19FN2OS, MW 390.47 g/mol) for analytical method development and quality control.

The molecular framework of 4-(4-Fluorophenyl)-N-phenethyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide (C23H19FN2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
