Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(4-((2-Methoxyethyl)(methyl)amino)phenyl)-2-phenyl-5-(trifluoromethyl)oxazole-4-carboxamide (CAS 1231243-91-6) is a high-purity analytical reference standard with the molecular formula C21H20F3N3O3 and a molecular weight of 419.40 g/mol.
The molecular framework of N-(4-((2-Methoxyethyl)(methyl)amino)phenyl)-2-phenyl-5-(trifluoromethyl)oxazole-4-carboxamide (C21H20F3N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
