Chemical Structure

1,5-Bis(phenylamino)anthracene-9,10-dione CAS 2944-27-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 326.47 g/mol gives 1,5-Bis(phenylamino)anthracene-9,10-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,5-Bis(phenylamino)anthracene-9,10-dione (CAS 2944-27-6), molecular formula C19H34O4 and molecular weight 326.47 g/mol, is a CATO reference standard with documented purity and traceability.

1,5-Bis(phenylamino)anthracene-9,10-dione (C19H34O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
