2,4-Dichloro-N-(5-cyano-2-(p-tolylthio)phenyl)benzamide CAS 303147-04-8 chemical structure

Description

The occurrence of 2,4-Dichloro-N-(5-cyano-2-(p-tolylthio)phenyl)benzamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,4-Dichloro-N-(5-cyano-2-(p-tolylthio)phenyl)benzamide (CAS 303147-04-8), a certified reference material (molecular formula C21H14Cl2N2OS, MW 413.32 g/mol) for analytical method development and quality control.

2,4-Dichloro-N-(5-cyano-2-(p-tolylthio)phenyl)benzamide (C21H14Cl2N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2,4-Dichloro-N-(5-cyano-2-(p-tolylthio)phenyl)benzamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
