Chemical Structure
Description
3-(4-Bromophenyl)-2-methyl-1-propene (CAS 83558-89-8) is a high-purity analytical reference standard with the molecular formula C10H11Br and a molecular weight of 211.10 g/mol.
Owing to bromine substitution, an aromatic ring system, 3-(4-Bromophenyl)-2-methyl-1-propene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-(4-Bromophenyl)-2-methyl-1-propene 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.
