Chemical Structure

1,2-Bis(4-(dimethylamino)phenyl)ethane-1,2-dione CAS 17078-27-2 chemical structure

Description

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.

CATO supplies 1,2-Bis(4-(dimethylamino)phenyl)ethane-1,2-dione (CAS 17078-27-2), a certified reference material (molecular formula C18H20N2O2, MW 296.36 g/mol) for analytical method development and quality control.

Structurally, 1,2-Bis(4-(dimethylamino)phenyl)ethane-1,2-dione (C18H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 296.36 g/mol, it falls into the medium-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.

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.
