Description

Compared with other compounds in its class, the molecular weight of 273.08 g/mol gives Methyl 8-bromo-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 8-bromo-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylate (CAS 823225-66-7), molecular formula C10H9BrO4 and molecular weight 273.08 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 8-bromo-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylate (C10H9BrO4) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Methyl 8-bromo-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylate 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.
