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.
2-(8-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acetic acid (CAS 1534732-17-6) is a high-purity analytical reference standard with the molecular formula C10H9BrO4 and a molecular weight of 273.08 g/mol.
The molecular framework of 2-(8-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acetic acid (C10H9BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
