Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.17 g/mol gives 1-(2-Bromo-1-(2-methoxyethoxy)ethyl)-2-methylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Bromo-1-(2-methoxyethoxy)ethyl)-2-methylbenzene (CAS 1249909-71-4) is a high-purity analytical reference standard with the molecular formula C12H17BrO2 and a molecular weight of 273.17 g/mol.
The molecular framework of 1-(2-Bromo-1-(2-methoxyethoxy)ethyl)-2-methylbenzene (C12H17BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
