Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 289.17 g/mol gives 2-Bromo-9,9-dimethyl-9H-xanthene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Bromo-9,9-dimethyl-9H-xanthene (CAS 1565868-91-8), a certified reference material (molecular formula C15H13BrO, MW 289.17 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 2-Bromo-9,9-dimethyl-9H-xanthene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2-Bromo-9,9-dimethyl-9H-xanthene 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.
