Description
Fmoc -Lys(5-FAM)-OH (CAS 925900-45-4), molecular formula C27H26N2O8 and molecular weight 506.50 g/mol, is a CATO reference standard with documented purity and traceability.
Fmoc -Lys(5-FAM)-OH (C27H26N2O8) contains a nitrogen-containing heterocyclic scaffold, 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 -Lys(5-FAM)-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.
