Chemical Structure
Description
The occurrence of 1-(2-Chloroethyl)-1h-pyrazole hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(2-Chloroethyl)-1h-pyrazole hydrochloride (CAS 1384430-68-5), a certified reference material (molecular formula C5H7ClN2HCl, MW 167.03 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H7ClN2HCl, 1-(2-Chloroethyl)-1h-pyrazole hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 167.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
