1-Cyclopentyl-4-ethynyl-1H-pyrazole CAS 2098065-88-2

Description

The occurrence of 1-Cyclopentyl-4-ethynyl-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Cyclopentyl-4-ethynyl-1H-pyrazole (CAS 2098065-88-2), a certified reference material (molecular formula C10H12N2, MW 160.22 g/mol) for analytical method development and quality control.

Structurally, 1-Cyclopentyl-4-ethynyl-1H-pyrazole (C10H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 160.22 g/mol, it falls into the medium-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.

As a certified reference material (CRM), 1-Cyclopentyl-4-ethynyl-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
