2-(4-Chlorophenyl)-1-morpholinoethane-1-thione CAS 42945-85-7

Description

2-(4-Chlorophenyl)-1-morpholinoethane-1-thione (CAS 42945-85-7), molecular formula C12H14ClNOS and molecular weight 255.76 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(4-Chlorophenyl)-1-morpholinoethane-1-thione (C12H14ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
