Chemical Structure

FKKSFKL-NH2 CAS 137168-33-3 chemical structure

Description

The molecular framework of FKKSFKL-NH2 (C45H73N11O8) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies FKKSFKL-NH2 (CAS 137168-33-3), a certified reference material (molecular formula C45H73N11O8, MW 896.13 g/mol) for analytical method development and quality control.

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 manufactures FKKSFKL-NH2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
