Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((tert-Butoxycarbonyl)amino)-3-(4-(tert-butyl)phenyl)propanoic acid (CAS 98375-50-9), molecular formula C18H27NO4 and molecular weight 321.41 g/mol, is a CATO reference standard with documented purity and traceability.
2-((tert-Butoxycarbonyl)amino)-3-(4-(tert-butyl)phenyl)propanoic acid (C18H27NO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
