Description
CATO manufactures (Val671)-Amyloid b/A4 Protein Precursor770 (H-4838.0001) 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.
(Val671)-Amyloid b/A4 Protein Precursor770 (H-4838.0001) (CAS 252256-43-2) is a high-purity analytical reference standard with the molecular formula C51H82N14O18 and a molecular weight of 1179.28 g/mol.
The molecular framework of (Val671)-Amyloid b/A4 Protein Precursor770 (H-4838.0001) (C51H82N14O18) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
