Chemical Structure
Description
CATO supplies Ac-Arg-Ser-Leu-Lys-AMC (CAS 259176-76-6), a certified reference material (molecular formula C33H51N9O8, MW 701.81 g/mol) for analytical method development and quality control.
The molecular framework of Ac-Arg-Ser-Leu-Lys-AMC (C33H51N9O8) is characterized by a nitrogen-containing heterocyclic scaffold, 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), Ac-Arg-Ser-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.
