Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 302.16 g/mol gives 2-Bromo-N-(2,4-dimethoxyphenyl)butanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-N-(2,4-dimethoxyphenyl)butanamide (CAS 1119451-52-3) is a high-purity analytical reference standard with the molecular formula C12H16BrNO3 and a molecular weight of 302.16 g/mol.
2-Bromo-N-(2,4-dimethoxyphenyl)butanamide (C12H16BrNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2-Bromo-N-(2,4-dimethoxyphenyl)butanamide 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.
