[1,2,4]Triazolo[1,5-a][1,3,5]triazin-7(6H)-one CAS 1489-03-8

Description

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.

[1,2,4]Triazolo[1,5-a][1,3,5]triazin-7(6H)-one (CAS 1489-03-8), molecular formula C4H3N5O and molecular weight 137.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [1,2,4]Triazolo[1,5-a][1,3,5]triazin-7(6H)-one (C4H3N5O) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), [1,2,4]Triazolo[1,5-a][1,3,5]triazin-7(6H)-one 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.
