3-(4-Bromo-1H-pyrazol-1-yl)-3-cyclopentylpropanenitrile CAS 1822969-98-1

Description

The occurrence of 3-(4-Bromo-1H-pyrazol-1-yl)-3-cyclopentylpropanenitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Bromo-1H-pyrazol-1-yl)-3-cyclopentylpropanenitrile (CAS 1822969-98-1), molecular formula C11H14BrN3 and molecular weight 268.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(4-Bromo-1H-pyrazol-1-yl)-3-cyclopentylpropanenitrile (C11H14BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 268.15 g/mol, it falls into the medium-molecular-weight range. 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.
