Chemical Structure
Description
CATO supplies 2-((3,5-Dimethyl-1H-pyrazol-4-yl)thio)pyrimidine (CAS 175277-26-6), a certified reference material (molecular formula C9H10N4S, MW 206.27 g/mol) for analytical method development and quality control.
2-((3,5-Dimethyl-1H-pyrazol-4-yl)thio)pyrimidine (C9H10N4S) 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. 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.
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.
