Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Pyridyldithio)-propionic acid-OSu.
3-(2-Pyridyldithio)-propionic acid-OSu (CAS 68181-17-9) is a high-purity analytical reference standard with the molecular formula C12H12N2O4S2 and a molecular weight of 312.36 g/mol.
Structurally, 3-(2-Pyridyldithio)-propionic acid-OSu (C12H12N2O4S2) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 312.36 g/mol, it falls into the moderately-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.
