Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 119.59 g/mol gives 5-Methyl-3,4-dihydro-2H-pyrrole hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Methyl-3,4-dihydro-2H-pyrrole hydrochloride (CAS 929269-44-3) is a high-purity analytical reference standard with the molecular formula C5H9NHCl and a molecular weight of 119.59 g/mol.
Based on its molecular formula C5H9NHCl, 5-Methyl-3,4-dihydro-2H-pyrrole hydrochloride contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 119.59 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.
