Chemical Structure
Description
The occurrence of Bz-D-Arg-pNA · HCl is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Bz-D-Arg-pNA · HCl (CAS 21653-41-8), molecular formula C19H22N6O4HCl and molecular weight 434.88 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bz-D-Arg-pNA · HCl (C19H22N6O4HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
CATO manufactures Bz-D-Arg-pNA · HCl 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.
