Chemical Structure
Description
Fmoc-D-Asp(OtBu)-OPfp (CAS 200335-75-7) is a high-purity analytical reference standard with the molecular formula C29H24F5NO6 and a molecular weight of 577.50 g/mol.
Fmoc-D-Asp(OtBu)-OPfp (C29H24F5NO6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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-D-Asp(OtBu)-OPfp 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.
