Chemical Structure
Description
The occurrence of 4-[(2E)-3-(5-Bromo-2-methoxyphenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-[(2E)-3-(5-Bromo-2-methoxyphenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate (CAS 306730-17-6), a certified reference material (molecular formula C27H25BrO4, MW 493.39 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, 4-[(2E)-3-(5-Bromo-2-methoxyphenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 493.39 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.
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.
