Chemical Structure
Description
2-Bromo-3-(3,5-dimethyl-4-methoxyphenyl)-1-propene (CAS 951893-08-6) is a high-purity analytical reference standard with the molecular formula C12H15BrO and a molecular weight of 255.15 g/mol.
Based on its molecular formula C12H15BrO, 2-Bromo-3-(3,5-dimethyl-4-methoxyphenyl)-1-propene contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 255.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
