Chemical Structure
Description
20989-69-9 3-Phenylpropionylglycine Glycine, N-(3-oxo-3-phenylpropyl)-, hydrochloride (CAS 20989-69-9), molecular formula C11H13NO3HCl and molecular weight 243.69 g/mol, is a CATO reference standard with documented purity and traceability.
20989-69-9 3-Phenylpropionylglycine Glycine, N-(3-oxo-3-phenylpropyl)-, hydrochloride (C11H13NO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
