Description
CATO manufactures 1,3,5,7-Tetrakis(phenylthio)anthracene-9,10-dione 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.
1,3,5,7-Tetrakis(phenylthio)anthracene-9,10-dione (CAS 52740-98-4) is a high-purity analytical reference standard with the molecular formula C38H24O2S4 and a molecular weight of 640.86 g/mol.
Based on its molecular formula C38H24O2S4, 1,3,5,7-Tetrakis(phenylthio)anthracene-9,10-dione contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 640.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
