4-((4-Chloro-2-fluorophenyl)amino)-6-methoxyquinazolin-7-ol CAS 193001-59-1

Description

4-((4-Chloro-2-fluorophenyl)amino)-6-methoxyquinazolin-7-ol (CAS 193001-59-1) is a high-purity analytical reference standard with the molecular formula C15H11ClFN3O2 and a molecular weight of 319.72 g/mol.

Based on its molecular formula C15H11ClFN3O2, 4-((4-Chloro-2-fluorophenyl)amino)-6-methoxyquinazolin-7-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
