Chemical Structure
Description
CATO supplies Fmoc-3-nitro-Tyr-OH (CAS 136590-09-5), a certified reference material (molecular formula C24H20N2O7, MW 448.43 g/mol) for analytical method development and quality control.
Fmoc-3-nitro-Tyr-OH (C24H20N2O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
As a certified reference material (CRM), Fmoc-3-nitro-Tyr-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.
