Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1-(4-methylnaphthalen-1-yl)ethan-1-one.
2-Bromo-1-(4-methylnaphthalen-1-yl)ethan-1-one (CAS 66728-56-1) is a high-purity analytical reference standard with the molecular formula C13H11BrO and a molecular weight of 263.13 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-1-(4-methylnaphthalen-1-yl)ethan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.13 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.
