Chemical Structure
Description
As a certified reference material (CRM), Fmoc-DL-Phe-OH 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.
CATO supplies Fmoc-DL-Phe-OH (CAS 126727-04-6), a certified reference material (molecular formula C24H21NO4, MW 387.43 g/mol) for analytical method development and quality control.
Fmoc-DL-Phe-OH (C24H21NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
