Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 420.34 g/mol gives tert-Butyl (1-(4-bromophenyl)ethyl)(4-methoxybenzyl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
tert-Butyl (1-(4-bromophenyl)ethyl)(4-methoxybenzyl)carbamate (CAS 1704096-58-1), molecular formula C21H26BrNO3 and molecular weight 420.34 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl (1-(4-bromophenyl)ethyl)(4-methoxybenzyl)carbamate (C21H26BrNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
