7-bromo-2,4,6-trichloro-8-fluoroquinazoline CAS 1698028-11-3

Description

Compared with other compounds in its class, the molecular weight of 340.45 g/mol gives 7-bromo-2,4,6-trichloro-8-fluoroquinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-bromo-2,4,6-trichloro-8-fluoroquinazoline (CAS 1698028-11-3) is a high-purity analytical reference standard with the molecular formula C8H11BrCl3FN2 and a molecular weight of 340.45 g/mol.

Structurally, 7-bromo-2,4,6-trichloro-8-fluoroquinazoline (C8H11BrCl3FN2) contains a nitrile group, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 340.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
