Chemical Structure

Z-His-Tyr-Tyr-OEt CAS 13053-63-9 chemical structure

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 Z-His-Tyr-Tyr-OEt (CAS 13053-63-9), a certified reference material (molecular formula C34H37N5O8, MW 643.69 g/mol) for analytical method development and quality control.

Z-His-Tyr-Tyr-OEt (C34H37N5O8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Z-His-Tyr-Tyr-OEt 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.
