Chemical Structure
Description
CATO supplies (Ser(PO?H?)2?2)-Tau Peptide (260-264) PAb Blocking trifluoroacetate salt (CAS 2022956-57-4), a certified reference material (molecular formula C20H36N5O13PC2HF3O2, MW 699.53 g/mol) for analytical method development and quality control.
The molecular framework of (Ser(PO?H?)2?2)-Tau Peptide (260-264) PAb Blocking trifluoroacetate salt (C20H36N5O13PC2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
