Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tau Peptide (401-411)-Lys-Lys trifluoroacetate salt (CAS 2022956-59-6) is a high-purity analytical reference standard with the molecular formula C60H103N21O20C2HF3O2 and a molecular weight of 1552.63 g/mol.
The molecular framework of Tau Peptide (401-411)-Lys-Lys trifluoroacetate salt (C60H103N21O20C2HF3O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Tau Peptide (401-411)-Lys-Lys trifluoroacetate salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
