Chemical Structure
Description
The occurrence of (S)-1-(D-Phenylalanyl)-N-((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)piperidine-2-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-1-(D-Phenylalanyl)-N-((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)piperidine-2-carboxamide (CAS 64815-81-2), molecular formula C27H36N8O5 and molecular weight 552.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (S)-1-(D-Phenylalanyl)-N-((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)piperidine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 552.63 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).
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), (S)-1-(D-Phenylalanyl)-N-((S)-5-guanidino-1-((4-nitrophenyl)amino)-1-oxopentan-2-yl)piperidine-2-carboxamide 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.
