Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 4-Bromo-N-(4-(tert-butyl)phenyl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.23 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.
4-Bromo-N-(4-(tert-butyl)phenyl)benzamide (CAS 746613-29-6) is a high-purity analytical reference standard with the molecular formula C17H18BrNO and a molecular weight of 332.23 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.
