Chemical Structure

H-D-Ala-DL-Ala-OH CAS 210687-33-5 chemical structure

Description

CATO supplies H-D-Ala-DL-Ala-OH (CAS 210687-33-5), a certified reference material (molecular formula C6H12N2O3, MW 160.17 g/mol) for analytical method development and quality control.

The molecular framework of H-D-Ala-DL-Ala-OH (C6H12N2O3) is characterized by an amino-acid-derived structure, 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.

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-D-Ala-DL-Ala-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.
