Chemical Structure
Description
CATO supplies 1-Bromo-3-methoxy-2-methylnaphthalene (CAS 2158298-62-3), a certified reference material (molecular formula C12H11BrO, MW 251.12 g/mol) for analytical method development and quality control.
1-Bromo-3-methoxy-2-methylnaphthalene (C12H11BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. 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.
As a certified reference material (CRM), 1-Bromo-3-methoxy-2-methylnaphthalene 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.
