Chemical Structure

4H,5H,6H,7H-Pyrazolo[1,5-a]pyrazin-2-amine CAS 1785544-01-5 chemical structure

Description

CATO supplies 4H,5H,6H,7H-Pyrazolo[1,5-a]pyrazin-2-amine (CAS 1785544-01-5), a certified reference material (molecular formula C6H10N4, MW 138.17 g/mol) for analytical method development and quality control.

Owing to a nitrile group, an aromatic ring system, 4H,5H,6H,7H-Pyrazolo[1,5-a]pyrazin-2-amine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
