CATO supplies Ethyl 2-{4-bromo-2-[(hydroxyimino)methyl]-6-methoxyphenoxy}acetate (CAS 338416-53-8), a certified reference material (molecular formula C12H14BrNO5, MW 332.15 g/mol) for analytical method development and quality control.
Ethyl 2-{4-bromo-2-[(hydroxyimino)methyl]-6-methoxyphenoxy}acetate (C12H14BrNO5) 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, 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.
