Chemical Structure
Description
The occurrence of (S)-3-(Pyridin-4-yl)-5-(pyrrolidin-2-yl)-1,2,4-oxadiazole dihydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-3-(Pyridin-4-yl)-5-(pyrrolidin-2-yl)-1,2,4-oxadiazole dihydrochloride (CAS 1609388-48-8), molecular formula C11H12N4OHCl and molecular weight 252.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-3-(Pyridin-4-yl)-5-(pyrrolidin-2-yl)-1,2,4-oxadiazole dihydrochloride (C11H12N4OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 252.70 g/mol, it falls into the medium-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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
