H-D-Ala-D-Ala-D-Ala-D-Ala-OH CAS 926-78-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including H-D-Ala-D-Ala-D-Ala-D-Ala-OH.

CATO supplies H-D-Ala-D-Ala-D-Ala-D-Ala-OH (CAS 926-78-3), a certified reference material (molecular formula C12H22N4O5, MW 302.33 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, H-D-Ala-D-Ala-D-Ala-D-Ala-OH is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-D-Ala-D-Ala-D-Ala-D-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.
