Chemical Structure
Description
The molecular framework of (7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-chlorophenyl)methanone (C15H10BrClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-chlorophenyl)methanone (CAS 175136-39-7) is a high-purity analytical reference standard with the molecular formula C15H10BrClO3 and a molecular weight of 353.60 g/mol.
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), (7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-chlorophenyl)methanone 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.
