Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-1-(3,4-dichlorobenzyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 895929-98-3) is a high-purity analytical reference standard with the molecular formula C10H8BrCl2N3 and a molecular weight of 321.00 g/mol.
4-Bromo-1-(3,4-dichlorobenzyl)-1,2-dihydro-3h-pyrazol-3-imine (C10H8BrCl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4-Bromo-1-(3,4-dichlorobenzyl)-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.
