Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 9-(Bromomethyl)-9H-xanthene (CAS 1493431-21-2), a certified reference material (molecular formula C14H11BrO, MW 275.14 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 9-(Bromomethyl)-9H-xanthene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 275.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 9-(Bromomethyl)-9H-xanthene 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.
