Chemical Structure

7-bromo-2,4-dichloro-8-fluoro-6-iodo-quinazoline CAS 2241720-34-1 chemical structure

Description

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.

CATO supplies 7-bromo-2,4-dichloro-8-fluoro-6-iodo-quinazoline (CAS 2241720-34-1), a certified reference material (molecular formula C8H11BrCl2FIN2, MW 431.90 g/mol) for analytical method development and quality control.

Owing to a nitrile group, fluorine/chlorine/bromine/iodine substitution, 7-bromo-2,4-dichloro-8-fluoro-6-iodo-quinazoline is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
