Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,4S)-1-(tert-Butoxycarbonyl)-4-(2-propyl-phenoxy)-2-pyrrolidinecarboxylic acid.
(2S,4S)-1-(tert-Butoxycarbonyl)-4-(2-propyl-phenoxy)-2-pyrrolidinecarboxylic acid (CAS 1354486-13-7), molecular formula C19H27NO5 and molecular weight 349.42 g/mol, is a CATO reference standard with documented purity and traceability.
(2S,4S)-1-(tert-Butoxycarbonyl)-4-(2-propyl-phenoxy)-2-pyrrolidinecarboxylic acid (C19H27NO5) contains a flavonoid 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).
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.
