Chemical Structure
Description
Fluorenylmethoxycarbonyl-L-Serine-L-Phenylalanine (CAS CATO-CPTD788873), molecular formula C28H28N2O6 and molecular weight 488.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Fluorenylmethoxycarbonyl-L-Serine-L-Phenylalanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 488.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Fluorenylmethoxycarbonyl-L-Serine-L-Phenylalanine 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.
