Chemical Structure
Description
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.
(2S)-2-({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)-3-(2H-1,2,3,4-tetrazol-5-yl)propanoic acid (CAS 954147-35-4), molecular formula C19H33N5O4 and molecular weight 395.50 g/mol, is a CATO reference standard with documented purity and traceability.
(2S)-2-({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)-3-(2H-1,2,3,4-tetrazol-5-yl)propanoic acid (C19H33N5O4) contains a steroid core, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
