Chemical Structure
Description
The occurrence of 1-(1-Bromobutan-2-yl)-4-methylbenzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(1-Bromobutan-2-yl)-4-methylbenzene (CAS 1135264-28-6) is a high-purity analytical reference standard with the molecular formula C11H15Br and a molecular weight of 227.14 g/mol.
Owing to bromine substitution, an aromatic ring system, 1-(1-Bromobutan-2-yl)-4-methylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 227.14 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.
