Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ac-Val-Asp-Val-Ala-Asp-aldehyde (pseudo acid) (CAS 194022-51-0), a certified reference material (molecular formula C23H37N5O10, MW 543.57 g/mol) for analytical method development and quality control.
The molecular framework of Ac-Val-Asp-Val-Ala-Asp-aldehyde (pseudo acid) (C23H37N5O10) is characterized by a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Ac-Val-Asp-Val-Ala-Asp-aldehyde (pseudo acid) 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.
