N,3-Bis(4-chlorophenyl)-5-(methylsulfanyl)thiophene-2-carboxamide CAS 477857-96-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N,3-Bis(4-chlorophenyl)-5-(methylsulfanyl)thiophene-2-carboxamide.

CATO supplies N,3-Bis(4-chlorophenyl)-5-(methylsulfanyl)thiophene-2-carboxamide (CAS 477857-96-8), a certified reference material (molecular formula C18H13Cl2NOS2, MW 394.34 g/mol) for analytical method development and quality control.

Structurally, N,3-Bis(4-chlorophenyl)-5-(methylsulfanyl)thiophene-2-carboxamide (C18H13Cl2NOS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 394.34 g/mol, it falls into the moderately-high-molecular-weight range. 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), N,3-Bis(4-chlorophenyl)-5-(methylsulfanyl)thiophene-2-carboxamide 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.
