Chemical Structure
Description
The molecular framework of 4-{2-[3-bromo-5-(4-fluorophenyl)-2-phenylpyrazolo[1,5-a]pyrimidin-6-yl]ethyl}morpholine (C24H22BrFN4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-{2-[3-bromo-5-(4-fluorophenyl)-2-phenylpyrazolo[1,5-a]pyrimidin-6-yl]ethyl}morpholine (CAS 866019-69-4) is a high-purity analytical reference standard with the molecular formula C24H22BrFN4O and a molecular weight of 481.36 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
