Chemical Structure
Description
1-(2-Bromoethyl)-2,4,5-trimethoxybenzene (CAS 28800-18-2) is a high-purity analytical reference standard with the molecular formula C11H15BrO3 and a molecular weight of 275.14 g/mol.
Structurally, 1-(2-Bromoethyl)-2,4,5-trimethoxybenzene (C11H15BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 275.14 g/mol, it falls into the medium-molecular-weight range. 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), 1-(2-Bromoethyl)-2,4,5-trimethoxybenzene 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.
