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-cyclopentyl-3-((3,3,3-trifluoropropoxy)methyl)-1H-pyrazole (CAS 1855949-30-2), molecular formula C12H16BrF3N2O and molecular weight 341.17 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-1-cyclopentyl-3-((3,3,3-trifluoropropoxy)methyl)-1H-pyrazole (C12H16BrF3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 4-Bromo-1-cyclopentyl-3-((3,3,3-trifluoropropoxy)methyl)-1H-pyrazole 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.
