Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 528.62 g/mol gives Z-Lys-OBzl · benzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Z-Lys-OBzl · benzenesulfonate (CAS 68973-36-4), molecular formula C21H26N2O4C6H6O3S and molecular weight 528.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Z-Lys-OBzl · benzenesulfonate (C21H26N2O4C6H6O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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), Z-Lys-OBzl · benzenesulfonate 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.
