Chemical Structure
Description
6-Chloro-N-(4-fluorophenethyl)pyrimidin-4-amine (CAS 1292632-69-9) is a high-purity analytical reference standard with the molecular formula C12H11ClFN3 and a molecular weight of 251.69 g/mol.
Based on its molecular formula C12H11ClFN3, 6-Chloro-N-(4-fluorophenethyl)pyrimidin-4-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.69 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.
