62298-43-5 3-Amino-7-(dimethylamino)phenothiazin-5-ium, salt with 2',4',5',7'-tetrabromo-3',6'-dihydroxyspiro(isobenzofuran-1(3H),9'-(9H)xanthen)-3-one (2:1) EINECS 263-491-2 (CAS 62298-43-5), molecular formula C14H20N3SCl and molecular weight 297.85 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H20N3SCl, 62298-43-5 3-Amino-7-(dimethylamino)phenothiazin-5-ium, salt with 2',4',5',7'-tetrabromo-3',6'-dihydroxyspiro(isobenzofuran-1(3H),9'-(9H)xanthen)-3-one (2:1) EINECS 263-491-2 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.85 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).
CATO manufactures 62298-43-5 3-Amino-7-(dimethylamino)phenothiazin-5-ium, salt with 2',4',5',7'-tetrabromo-3',6'-dihydroxyspiro(isobenzofuran-1(3H),9'-(9H)xanthen)-3-one (2:1) EINECS 263-491-2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation.
