2-(5-Chloro-2-phenoxyphenyl)-1-morpholinoethanethione CAS 70958-19-9

Description

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.

2-(5-Chloro-2-phenoxyphenyl)-1-morpholinoethanethione (CAS 70958-19-9) is a high-purity analytical reference standard with the molecular formula C18H18ClNO2S and a molecular weight of 347.86 g/mol.

The molecular framework of 2-(5-Chloro-2-phenoxyphenyl)-1-morpholinoethanethione (C18H18ClNO2S) is characterized by a steroid 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 its high hydrophobicity (logP), 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).

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.
