Chemical Structure
Description
The occurrence of (S)-Ethyl 3-amino-3-(p-tolyl)propanoate hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (S)-Ethyl 3-amino-3-(p-tolyl)propanoate hydrochloride (CAS 402828-01-7), a certified reference material (molecular formula C12H17NO2HCl, MW 243.73 g/mol) for analytical method development and quality control.
(S)-Ethyl 3-amino-3-(p-tolyl)propanoate hydrochloride (C12H17NO2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
