3-(4-Fluorophenyl)-6-(4-methoxyphenyl)pyrazolo[1,5-a]pyrimidin-7-amine (CAS 865657-97-2) is a high-purity analytical reference standard with the molecular formula C19H15FN4O and a molecular weight of 334.35 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 3-(4-Fluorophenyl)-6-(4-methoxyphenyl)pyrazolo[1,5-a]pyrimidin-7-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
