Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 231.10 g/mol gives 1-(2-Bromo-2-methylpropyl)-4-fluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Bromo-2-methylpropyl)-4-fluorobenzene (CAS 1240520-37-9) is a high-purity analytical reference standard with the molecular formula C10H12BrF and a molecular weight of 231.10 g/mol.
1-(2-Bromo-2-methylpropyl)-4-fluorobenzene (C10H12BrF) contains fluorine/bromine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(2-Bromo-2-methylpropyl)-4-fluorobenzene 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.
