Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.20 g/mol gives Ethyl 1-(2-bromobutanoyl)piperidine-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 1-(2-bromobutanoyl)piperidine-4-carboxylate (CAS 1119453-06-3), a certified reference material (molecular formula C12H20BrNO3, MW 306.20 g/mol) for analytical method development and quality control.
Ethyl 1-(2-bromobutanoyl)piperidine-4-carboxylate (C12H20BrNO3) contains an amide group, a carboxylic acid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
