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-(2-Bromo-4-iodophenyl)-1,3-dioxolane (CAS 203583-95-3) is a high-purity analytical reference standard with the molecular formula C9H8BrIO2 and a molecular weight of 354.97 g/mol.
The molecular framework of 2-(2-Bromo-4-iodophenyl)-1,3-dioxolane (C9H8BrIO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
