Description
As a certified reference material (CRM), Substance P 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.
Substance P (CAS 33507-63-0) is a high-purity analytical reference standard with the molecular formula C63H98N18O13S and a molecular weight of 1347.60 g/mol.
Structurally, Substance P (C63H98N18O13S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 1347.60 g/mol, it falls into the high-molecular-weight range. 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.
