7-(4-Phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine CAS 303145-65-5

Description

The molecular framework of 7-(4-Phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine (C17H13N5O) is characterized by a steroid core, an amide group, 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).

7-(4-Phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine (CAS 303145-65-5), molecular formula C17H13N5O and molecular weight 303.32 g/mol, is a CATO reference standard with documented purity and traceability.

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), 7-(4-Phenoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine 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.
