Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.08 g/mol gives 7-Bromo-8-methoxyquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Bromo-8-methoxyquinoline (CAS 36748-99-9), molecular formula C10H8BrNO and molecular weight 238.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 7-Bromo-8-methoxyquinoline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 7-Bromo-8-methoxyquinoline 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.
