Chemical Structure
Description
CATO supplies Fmoc-l-beta-homotryptophan (CAS 353245-98-4), a certified reference material (molecular formula C27H24N2O4, MW 440.49 g/mol) for analytical method development and quality control.
The molecular framework of Fmoc-l-beta-homotryptophan (C27H24N2O4) is characterized by a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Fmoc-l-beta-homotryptophan 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.
