Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
[1,1'-Biphenyl]-3-propanoic acid, α-amino-2',4'-dichloro-4-hydroxy-5-(phosphonomethyl)-, (αS)- (CAS 174575-40-7), molecular formula C16H16Cl2NO6P and molecular weight 420.18 g/mol, is a CATO reference standard with documented purity and traceability.
[1,1'-Biphenyl]-3-propanoic acid, α-amino-2',4'-dichloro-4-hydroxy-5-(phosphonomethyl)-, (αS)- (C16H16Cl2NO6P) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.
