2-(1-((3-Amino-4-bromo-1h-pyrazol-1-yl)methyl)cyclopropyl)acetonitrile CAS 1494097-03-8

Description

2-(1-((3-Amino-4-bromo-1h-pyrazol-1-yl)methyl)cyclopropyl)acetonitrile (CAS 1494097-03-8), molecular formula C9H11BrN4 and molecular weight 255.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(1-((3-Amino-4-bromo-1h-pyrazol-1-yl)methyl)cyclopropyl)acetonitrile (C9H11BrN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
