2-((5H-[1,2,4]Triazino[5,6-b]indol-3-yl)thio)-N-(2-methoxyphenyl)acetamide (CAS 332176-64-4), molecular formula C18H15N5O2S and molecular weight 365.41 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H15N5O2S, 2-((5H-[1,2,4]Triazino[5,6-b]indol-3-yl)thio)-N-(2-methoxyphenyl)acetamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 365.41 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).
CATO manufactures 2-((5H-[1,2,4]Triazino[5,6-b]indol-3-yl)thio)-N-(2-methoxyphenyl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
