2-((4-Allyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-bromo-4,6-difluorophenyl)acetamide CAS 618879-88-2

Description

2-((4-Allyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-bromo-4,6-difluorophenyl)acetamide (CAS 618879-88-2), molecular formula C17H13BrF2N4OS2 and molecular weight 471.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-Allyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-bromo-4,6-difluorophenyl)acetamide (C17H13BrF2N4OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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), 2-((4-Allyl-5-(thiophen-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-bromo-4,6-difluorophenyl)acetamide 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.
