Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
D-Lys(Z)-Pro-Arg-pNA diacetate (CAS 108963-70-8) is a high-purity analytical reference standard with the molecular formula C31H43N9O7C2H4O2 and a molecular weight of 713.79 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, D-Lys(Z)-Pro-Arg-pNA diacetate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 713.79 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).
As a certified reference material (CRM), D-Lys(Z)-Pro-Arg-pNA diacetate 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.
