3-Chloro-5-((4-ethylpiperazin-1-yl)sulfonyl)pyridine-4-thiol (CAS 1352516-01-8), molecular formula C11H16ClN3O2S2 and molecular weight 321.85 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H16ClN3O2S2, 3-Chloro-5-((4-ethylpiperazin-1-yl)sulfonyl)pyridine-4-thiol contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
