Description
CATO manufactures Ac-Ala-Ala-Ser(PO3H2)-Pro-Arg-pNA 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.
Ac-Ala-Ala-Ser(PO3H2)-Pro-Arg-pNA trifluoroacetate salt (CAS 202739-37-5) is a high-purity analytical reference standard with the molecular formula C28H43N10O12PC2HF3O2 and a molecular weight of 856.71 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution, Ac-Ala-Ala-Ser(PO3H2)-Pro-Arg-pNA trifluoroacetate salt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 856.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
