(1-Methyl-2-oxo-2-phenyl-ethyl)-carbamic acid tert-butyl ester (CAS 79821-73-1), molecular formula C14H19NO3 and molecular weight 249.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-Methyl-2-oxo-2-phenyl-ethyl)-carbamic acid tert-butyl ester (C14H19NO3) 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 its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
