Chemical Structure
Description
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.
CATO supplies H-Ala-Ala-Ala-OMe acetate salt (CAS 84794-58-1), a certified reference material (molecular formula C10H19N3O4C2H4O2, MW 305.33 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H19N3O4C2H4O2, H-Ala-Ala-Ala-OMe acetate salt contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 305.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), H-Ala-Ala-Ala-OMe acetate salt 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.
