Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 135.21 g/mol gives 1-Cyclopentyl-1H-pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Cyclopentyl-1H-pyrrole (CAS 752205-97-3), a certified reference material (molecular formula C9H13N, MW 135.21 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H13N, 1-Cyclopentyl-1H-pyrrole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 135.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
