N-(4-(Benzo[d]oxazol-2-yl)phenyl)-5-chlorothiophene-2-carboxamide CAS 477503-79-0

Description

Compared with other compounds in its class, the molecular weight of 354.81 g/mol gives N-(4-(Benzo[d]oxazol-2-yl)phenyl)-5-chlorothiophene-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N-(4-(Benzo[d]oxazol-2-yl)phenyl)-5-chlorothiophene-2-carboxamide (CAS 477503-79-0), a certified reference material (molecular formula C18H11ClN2O2S, MW 354.81 g/mol) for analytical method development and quality control.

The molecular framework of N-(4-(Benzo[d]oxazol-2-yl)phenyl)-5-chlorothiophene-2-carboxamide (C18H11ClN2O2S) 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. 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-(4-(Benzo[d]oxazol-2-yl)phenyl)-5-chlorothiophene-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.
