Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 333.95 g/mol gives 7-Bromo-3-iodoisoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 7-Bromo-3-iodoisoquinoline (CAS 2089318-84-1), a certified reference material (molecular formula C9H5BrIN, MW 333.95 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromo-3-iodoisoquinoline (C9H5BrIN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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.
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.
