Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tau Peptide (337-368) (Repeat 4 Domain) trifluoroacetate salt.
CATO supplies Tau Peptide (337-368) (Repeat 4 Domain) trifluoroacetate salt (CAS 330456-27-4), a certified reference material (molecular formula C150H248N44O50C2HF3O2, MW 3581.91 g/mol) for analytical method development and quality control.
The molecular framework of Tau Peptide (337-368) (Repeat 4 Domain) trifluoroacetate salt (C150H248N44O50C2HF3O2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Tau Peptide (337-368) (Repeat 4 Domain) trifluoroacetate salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
