3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carbonyl chloride CAS 306934-86-1

Description

As a certified reference material (CRM), 3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carbonyl chloride 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.

CATO supplies 3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carbonyl chloride (CAS 306934-86-1), a certified reference material (molecular formula C10H9ClO3, MW 212.63 g/mol) for analytical method development and quality control.

3,4-Dihydro-2H-benzo[b][1,4]dioxepine-7-carbonyl chloride (C10H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
