Chemical Structure
Description
The molecular framework of Tau Peptide (306-317) trifluoroacetate salt (C65H109N15O18C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Tau Peptide (306-317) trifluoroacetate salt (CAS 1003007-59-7), molecular formula C65H109N15O18C2HF3O2 and molecular weight 1502.70 g/mol, is a CATO reference standard with documented purity and traceability.
