Chemical Structure
Description
The occurrence of 1-(1-Bromoethyl)-3-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-Bromoethyl)-3-methylbenzene (CAS 88563-82-0) is a high-purity analytical reference standard with the molecular formula C9H11Br and a molecular weight of 199.09 g/mol.
Owing to bromine substitution, an aromatic ring system, 1-(1-Bromoethyl)-3-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.09 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.
