Chemical Structure

(4-Methylphenyl)[1-[(4-methylphenyl)sulfonyl]-1H-pyrrol-3-yl]methanone CAS 1393442-27-7 chemical structure

Description

The occurrence of (4-Methylphenyl)[1-[(4-methylphenyl)sulfonyl]-1H-pyrrol-3-yl]methanone is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4-Methylphenyl)[1-[(4-methylphenyl)sulfonyl]-1H-pyrrol-3-yl]methanone (CAS 1393442-27-7), molecular formula C19H17NO3S and molecular weight 339.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4-Methylphenyl)[1-[(4-methylphenyl)sulfonyl]-1H-pyrrol-3-yl]methanone (C19H17NO3S) 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. 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.

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.
