Chemical Structure
Description
The occurrence of 1-(3-Bromo-2-methylpropyl)-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-(3-Bromo-2-methylpropyl)-4-methylbenzene (CAS 66229-90-1) 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-(3-Bromo-2-methylpropyl)-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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
