Chemical Structure

D-Valyl-D-alanine CAS 1115-74-8 chemical structure

Description

As a certified reference material (CRM), D-Valyl-D-alanine 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.

CATO supplies D-Valyl-D-alanine (CAS 1115-74-8), a certified reference material (molecular formula C8H16N2O3, MW 188.22 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, D-Valyl-D-alanine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
