Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromomethyl-2,3-dihydrobenzo[1,4]dioxine.
CATO supplies 2-Bromomethyl-2,3-dihydrobenzo[1,4]dioxine (CAS 2164-34-3), a certified reference material (molecular formula C9H9BrO2, MW 229.07 g/mol) for analytical method development and quality control.
2-Bromomethyl-2,3-dihydrobenzo[1,4]dioxine (C9H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-Bromomethyl-2,3-dihydrobenzo[1,4]dioxine 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.
