Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-Bromo-4-fluorobenzyl)-4-methylpiperazine (CAS 1248702-49-9), molecular formula C12H16BrFN2 and molecular weight 287.17 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Bromo-4-fluorobenzyl)-4-methylpiperazine (C12H16BrFN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 1-(2-Bromo-4-fluorobenzyl)-4-methylpiperazine 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.
