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.
LL-37 FK-13 trifluoroacetate salt (CAS 717919-68-1), molecular formula C80H135N25O17C2HF3O2 and molecular weight 1833.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of LL-37 FK-13 trifluoroacetate salt (C80H135N25O17C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
As a certified reference material (CRM), LL-37 FK-13 trifluoroacetate 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.
