Chemical Structure
Description
The occurrence of Ethyl 2-(3-(4-methoxyphenyl)ureido)acetate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-(3-(4-methoxyphenyl)ureido)acetate (CAS 108482-18-4), molecular formula C12H16N2O4 and molecular weight 252.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(3-(4-methoxyphenyl)ureido)acetate (C12H16N2O4) is characterized by an amino-acid-derived structure, 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.
