Description
Compared with other compounds in its class, the molecular weight of 487.60 g/mol gives H-D-Ala-Leu-Lys-AMC distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies H-D-Ala-Leu-Lys-AMC (CAS 104881-72-3), a certified reference material (molecular formula C25H37N5O5, MW 487.60 g/mol) for analytical method development and quality control.
H-D-Ala-Leu-Lys-AMC (C25H37N5O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Leu-Lys-AMC 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.
