Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Mal-amido-PEG3-C1-PFP ester (CAS 2101206-13-5) is a high-purity analytical reference standard with the molecular formula C21H21F5N2O8 and a molecular weight of 524.39 g/mol.
Mal-amido-PEG3-C1-PFP ester (C21H21F5N2O8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
