Compared with other compounds in its class, the molecular weight of 213.23 g/mol gives 4-Aminophenyl benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Aminophenyl benzoate (CAS 720-98-9) is a high-purity analytical reference standard with the molecular formula C13H11NO2 and a molecular weight of 213.23 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Aminophenyl benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
