Methyl 3-((5-bromo-2-hydroxy-3-methoxybenzylidene)amino)benzoate (CAS 477848-29-6), molecular formula C16H14BrNO4 and molecular weight 364.19 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 3-((5-bromo-2-hydroxy-3-methoxybenzylidene)amino)benzoate (C16H14BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
