Chemical Structure

1-((2-Ethylhexyl)amino)-4-(methylamino)anthracene-9,10-dione CAS 75476-94-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1-((2-Ethylhexyl)amino)-4-(methylamino)anthracene-9,10-dione (CAS 75476-94-7) is a high-purity analytical reference standard with the molecular formula C23H28N2O2 and a molecular weight of 364.48 g/mol.

The molecular framework of 1-((2-Ethylhexyl)amino)-4-(methylamino)anthracene-9,10-dione (C23H28N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
