Chemical Structure

2-Bromo-4-(3-methylphenyl)-1-butene CAS 731772-19-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 225.12 g/mol gives 2-Bromo-4-(3-methylphenyl)-1-butene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-4-(3-methylphenyl)-1-butene (CAS 731772-19-3), molecular formula C11H13Br and molecular weight 225.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to bromine substitution, an aromatic ring system, 2-Bromo-4-(3-methylphenyl)-1-butene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 225.12 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.

As a certified reference material (CRM), 2-Bromo-4-(3-methylphenyl)-1-butene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
