Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.24 g/mol gives 7-Hydroxy-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 7-Hydroxy-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic acid (CAS 63059-40-5), a certified reference material (molecular formula C8H8N4O3S, MW 240.24 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 7-Hydroxy-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 7-Hydroxy-5-methyl-2-(methylthio)-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
