Description
As a certified reference material (CRM), Amyloid β-Protein (1-40) trifluoroacetate salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Amyloid β-Protein (1-40) trifluoroacetate salt (CAS 131438-79-4), a certified reference material (molecular formula C194H295N53O58SC2HF3O2, MW 4443.89 g/mol) for analytical method development and quality control.
The molecular framework of Amyloid β-Protein (1-40) trifluoroacetate salt (C194H295N53O58SC2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
