N-(3-Chloro-4-fluorophenyl)-7-(furan-3-yl)quinazolin-4-amine CAS 194851-13-3

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.

N-(3-Chloro-4-fluorophenyl)-7-(furan-3-yl)quinazolin-4-amine (CAS 194851-13-3), molecular formula C18H11ClFN3O and molecular weight 339.75 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(3-Chloro-4-fluorophenyl)-7-(furan-3-yl)quinazolin-4-amine (C18H11ClFN3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
