Chemical Structure
Description
Tau Peptide (74-102) (Exon 3/Insert 2 Domain) trifluoroacetate salt (CAS 1322695-34-0) is a high-purity analytical reference standard with the molecular formula C124H198N34O46C2HF3O2 and a molecular weight of 3015.16 g/mol.
Tau Peptide (74-102) (Exon 3/Insert 2 Domain) trifluoroacetate salt (C124H198N34O46C2HF3O2) contains a nitrogen-containing heterocyclic scaffold, 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).
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 (74-102) (Exon 3/Insert 2 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.
