Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-Methyl 2-((S)-2-amino-4-methylpentanamido)-3-phenylpropanoate 2,2,2-trifluoroacetate.
CATO supplies (S)-Methyl 2-((S)-2-amino-4-methylpentanamido)-3-phenylpropanoate 2,2,2-trifluoroacetate (CAS 90072-18-7), a certified reference material (molecular formula C16H24N2O3C2HF3O2, MW 406.40 g/mol) for analytical method development and quality control.
(S)-Methyl 2-((S)-2-amino-4-methylpentanamido)-3-phenylpropanoate 2,2,2-trifluoroacetate (C16H24N2O3C2HF3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
