Chemical Structure
Description
The molecular framework of 4-(2-((tert-Butoxycarbonyl)amino)ethyl)benzoic acid (C14H19NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-(2-((tert-Butoxycarbonyl)amino)ethyl)benzoic acid (CAS 132690-91-6), molecular formula C14H19NO4 and molecular weight 265.30 g/mol, is a CATO reference standard with documented purity and traceability.
