Chemical Structure
Description
1,3,5,7-Tetrakis((4-butylphenyl)thio)anthracene-9,10-dione (CAS 113461-28-2), molecular formula C54H56O2S4 and molecular weight 865.28 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3,5,7-Tetrakis((4-butylphenyl)thio)anthracene-9,10-dione (C54H56O2S4) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 865.28 g/mol, it falls into the high-molecular-weight range. 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.
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.
