Chemical Structure

H-arg(Z)2-oh CAS 4125-79-5 chemical structure

Description

As a certified reference material (CRM), H-arg(Z)2-oh 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 H-arg(Z)2-oh (CAS 4125-79-5), a certified reference material (molecular formula C22H26N4O6, MW 442.47 g/mol) for analytical method development and quality control.

The molecular framework of H-arg(Z)2-oh (C22H26N4O6) 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. 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.
