1,4,5,8-Tetrakis(m-tolylamino)anthracene-9,10-dione CAS 119379-80-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4,5,8-Tetrakis(m-tolylamino)anthracene-9,10-dione.

1,4,5,8-Tetrakis(m-tolylamino)anthracene-9,10-dione (CAS 119379-80-5), molecular formula C42H36N4O2 and molecular weight 628.76 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,4,5,8-Tetrakis(m-tolylamino)anthracene-9,10-dione (C42H36N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 628.76 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
