Chemical Structure
Description
CATO supplies (5-Bromo-2,3-dimethoxyphenyl)methanol (CAS 86232-34-0), a certified reference material (molecular formula C9H11BrO3, MW 247.09 g/mol) for analytical method development and quality control.
(5-Bromo-2,3-dimethoxyphenyl)methanol (C9H11BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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.
As a certified reference material (CRM), (5-Bromo-2,3-dimethoxyphenyl)methanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
