1-{[5-(thiophen-2-yl)-1,2,4-oxadiazol-3-yl]methyl}piperazine dihydrochloride CAS 1269151-57-6

Description

The occurrence of 1-{[5-(thiophen-2-yl)-1,2,4-oxadiazol-3-yl]methyl}piperazine dihydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-{[5-(thiophen-2-yl)-1,2,4-oxadiazol-3-yl]methyl}piperazine dihydrochloride (CAS 1269151-57-6), molecular formula C11H14N4OSHCl and molecular weight 286.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 1-{[5-(thiophen-2-yl)-1,2,4-oxadiazol-3-yl]methyl}piperazine dihydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
