CATO supplies 3-Benzyl-3h-[1,2,3]triazolo[4,5-d]pyrimidine-7-thiol (CAS 13925-59-2), a certified reference material (molecular formula C11H9N5S, MW 243.29 g/mol) for analytical method development and quality control.
3-Benzyl-3h-[1,2,3]triazolo[4,5-d]pyrimidine-7-thiol (C11H9N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
