Description
CATO manufactures 1-(2-(Chloromethyl)phenyl)-1H-pyrazole hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 1-(2-(Chloromethyl)phenyl)-1H-pyrazole hydrochloride (CAS 1255717-84-0), a certified reference material (molecular formula C10H9ClN2HCl, MW 229.10 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H9ClN2HCl, 1-(2-(Chloromethyl)phenyl)-1H-pyrazole hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.10 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.
