Chemical Structure

Z-Tyr-OH CAS 1164-16-5 chemical structure

Description

Z-Tyr-OH (CAS 1164-16-5) is a high-purity analytical reference standard with the molecular formula C17H17NO5 and a molecular weight of 315.32 g/mol.

The molecular framework of Z-Tyr-OH (C17H17NO5) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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