Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(2-((4-(3-Chlorophenyl)piperazin-1-yl)sulfonyl)ethyl)-2-(thiophen-2-yl)acetamide (CAS 897613-19-3), molecular formula C18H22ClN3O3S2 and molecular weight 427.97 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H22ClN3O3S2, N-(2-((4-(3-Chlorophenyl)piperazin-1-yl)sulfonyl)ethyl)-2-(thiophen-2-yl)acetamide contains a steroid core, 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 427.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
