Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 3-((4-(Tert-butyl)benzyl)oxy)-N-(4-(trifluoromethyl)phenyl)thiophene-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 433.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-((4-(Tert-butyl)benzyl)oxy)-N-(4-(trifluoromethyl)phenyl)thiophene-2-carboxamide (CAS 344272-91-9) is a high-purity analytical reference standard with the molecular formula C23H22F3NO2S and a molecular weight of 433.49 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.
