Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Methyl (S)-2-((tert-butoxycarbonyl)amino)-2-(4-hydroxyphenyl)acetate (CAS 225517-15-7), a certified reference material (molecular formula C14H19NO5, MW 281.30 g/mol) for analytical method development and quality control.
Methyl (S)-2-((tert-butoxycarbonyl)amino)-2-(4-hydroxyphenyl)acetate (C14H19NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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.
