Chemical Structure
Description
Amyloid β-Protein (22-35) (CAS 144189-71-9), molecular formula C59H102N16O21S and molecular weight 1403.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Amyloid β-Protein (22-35) (C59H102N16O21S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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 Amyloid β-Protein (22-35) 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.
