3-(2-Chloro-5-fluoropyrimidin-4-yloxy)-phenylamine CAS 1643967-64-9

Description

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.

3-(2-Chloro-5-fluoropyrimidin-4-yloxy)-phenylamine (CAS 1643967-64-9) is a high-purity analytical reference standard with the molecular formula C10H7ClFN3O and a molecular weight of 239.63 g/mol.

Based on its molecular formula C10H7ClFN3O, 3-(2-Chloro-5-fluoropyrimidin-4-yloxy)-phenylamine 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 239.63 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).

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.
