2-((4-Ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-ethylphenyl)acetamide CAS 578723-85-0 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 2-((4-Ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-ethylphenyl)acetamide.

CATO supplies 2-((4-Ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-ethylphenyl)acetamide (CAS 578723-85-0), a certified reference material (molecular formula C18H20N6OS, MW 368.46 g/mol) for analytical method development and quality control.

The molecular framework of 2-((4-Ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-ethylphenyl)acetamide (C18H20N6OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-Ethyl-5-(pyrazin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-ethylphenyl)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.
