Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-3-{4-[(4-bromophenyl)methoxy]phenyl}-N-(3-methoxyphenyl)prop-2-enamide.
(2E)-3-{4-[(4-bromophenyl)methoxy]phenyl}-N-(3-methoxyphenyl)prop-2-enamide (CAS 477889-44-4), molecular formula C23H20BrNO3 and molecular weight 438.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2E)-3-{4-[(4-bromophenyl)methoxy]phenyl}-N-(3-methoxyphenyl)prop-2-enamide (C23H20BrNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 438.31 g/mol, it falls into the moderately-high-molecular-weight range. 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.
