5-Methyl-[1,2,4]triazolo[4,3-a][1,3,5]triazin-7(1H)-one CAS 200350-23-8

Description

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

5-Methyl-[1,2,4]triazolo[4,3-a][1,3,5]triazin-7(1H)-one (CAS 200350-23-8), molecular formula C5H5N5O and molecular weight 151.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 5-Methyl-[1,2,4]triazolo[4,3-a][1,3,5]triazin-7(1H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
