Chemical Structure
Description
The occurrence of 4-Bromo-5,7-difluoro-2-methylquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-5,7-difluoro-2-methylquinoline (CAS 1189105-77-8) is a high-purity analytical reference standard with the molecular formula C10H6BrF2N and a molecular weight of 258.06 g/mol.
4-Bromo-5,7-difluoro-2-methylquinoline (C10H6BrF2N) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 4-Bromo-5,7-difluoro-2-methylquinoline 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.
