Chemical Structure
Description
The occurrence of 3-(((Benzyloxy)carbonyl)amino)-3-(m-tolyl)propanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(((Benzyloxy)carbonyl)amino)-3-(m-tolyl)propanoic acid (CAS 778598-14-4), molecular formula C18H19NO4 and molecular weight 313.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(((Benzyloxy)carbonyl)amino)-3-(m-tolyl)propanoic acid (C18H19NO4) is characterized by a flavonoid core, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
