Compared with other compounds in its class, the molecular weight of 221.69 g/mol gives 1-(3-Chlorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(3-Chlorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine (CAS 1004643-48-4), a certified reference material (molecular formula C11H12ClN3, MW 221.69 g/mol) for analytical method development and quality control.
1-(3-Chlorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine (C11H12ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 1-(3-Chlorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine 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.
