Chemical Structure
Description
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.
CATO supplies (R)-(6-bromo-2,3-dihydrobenzo[b][1,4]dioxin-2-yl)methanol (CAS 1263285-26-2), a certified reference material (molecular formula C9H9BrO3, MW 245.07 g/mol) for analytical method development and quality control.
(R)-(6-bromo-2,3-dihydrobenzo[b][1,4]dioxin-2-yl)methanol (C9H9BrO3) 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.
As a certified reference material (CRM), (R)-(6-bromo-2,3-dihydrobenzo[b][1,4]dioxin-2-yl)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.
