2-(1-Methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-6-tosylpyrazolo[1,5-a]pyrimidin-7-amine CAS 920529-93-7 chemical structure

Description

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.

CATO supplies 2-(1-Methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-6-tosylpyrazolo[1,5-a]pyrimidin-7-amine (CAS 920529-93-7), a certified reference material (molecular formula C18H15F3N6O2S, MW 436.41 g/mol) for analytical method development and quality control.

Structurally, 2-(1-Methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-6-tosylpyrazolo[1,5-a]pyrimidin-7-amine (C18H15F3N6O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 436.41 g/mol, it falls into the moderately-high-molecular-weight range. 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.
