Description

As a certified reference material (CRM), 2-((4-(4-Chlorophenyl)-5-(2-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(1-cyano-1-cyclopropylethyl)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.

2-((4-(4-Chlorophenyl)-5-(2-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(1-cyano-1-cyclopropylethyl)acetamide (CAS 851890-45-4), molecular formula C23H22ClN5O2S and molecular weight 467.97 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-(4-Chlorophenyl)-5-(2-methoxyphenyl)-4H-1,2,4-triazol-3-yl)thio)-N-(1-cyano-1-cyclopropylethyl)acetamide (C23H22ClN5O2S) 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 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
