Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 442.23 g/mol gives Brimonidine x L-(+)-Tartaric acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Brimonidine x L-(+)-Tartaric acid (CAS 59803-99-5) is a high-purity analytical reference standard with the molecular formula C11H10BrN5x(C4H6O6) and a molecular weight of 442.23 g/mol.
Brimonidine x L-(+)-Tartaric acid (C11H10BrN5x(C4H6O6)) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Brimonidine x L-(+)-Tartaric acid 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.
