Chemical Structure

4-((4-Chlorophenyl)sulfonyl)-N-(2-methoxyethyl)-2-(o-tolyl)oxazol-5-amine CAS 883247-79-8 chemical structure

Description

The occurrence of 4-((4-Chlorophenyl)sulfonyl)-N-(2-methoxyethyl)-2-(o-tolyl)oxazol-5-amine is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-((4-Chlorophenyl)sulfonyl)-N-(2-methoxyethyl)-2-(o-tolyl)oxazol-5-amine (CAS 883247-79-8) is a high-purity analytical reference standard with the molecular formula C19H19ClN2O4S and a molecular weight of 406.88 g/mol.

The molecular framework of 4-((4-Chlorophenyl)sulfonyl)-N-(2-methoxyethyl)-2-(o-tolyl)oxazol-5-amine (C19H19ClN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
