4-Bromo-1-cyclopropoxy-2-ethylbenzene CAS 1243395-01-8

Description

Compared with other compounds in its class, the molecular weight of 241.12 g/mol gives 4-Bromo-1-cyclopropoxy-2-ethylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-1-cyclopropoxy-2-ethylbenzene (CAS 1243395-01-8) is a high-purity analytical reference standard with the molecular formula C11H13BrO and a molecular weight of 241.12 g/mol.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 4-Bromo-1-cyclopropoxy-2-ethylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 241.12 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.
