Chemical Structure

H-Leu-Tyr-OH CAS 968-21-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 294.35 g/mol gives H-Leu-Tyr-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

H-Leu-Tyr-OH (CAS 968-21-8) is a high-purity analytical reference standard with the molecular formula C15H22N2O4 and a molecular weight of 294.35 g/mol.

The molecular framework of H-Leu-Tyr-OH (C15H22N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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), H-Leu-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.
