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)-1-(3-Bromophenyl)-3-(4-chlorophenyl)prop-2-en-1-one.
(2E)-1-(3-Bromophenyl)-3-(4-chlorophenyl)prop-2-en-1-one (CAS 680997-47-1) is a high-purity analytical reference standard with the molecular formula C15H10BrClO and a molecular weight of 321.60 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system, (2E)-1-(3-Bromophenyl)-3-(4-chlorophenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.60 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.
