1,4-Diamino-2-(4-(heptyloxy)phenyl)anthracene-9,10-dione CAS 92135-76-7

Description

The occurrence of 1,4-Diamino-2-(4-(heptyloxy)phenyl)anthracene-9,10-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,4-Diamino-2-(4-(heptyloxy)phenyl)anthracene-9,10-dione (CAS 92135-76-7), molecular formula C27H28N2O3 and molecular weight 428.52 g/mol, is a CATO reference standard with documented purity and traceability.

1,4-Diamino-2-(4-(heptyloxy)phenyl)anthracene-9,10-dione (C27H28N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
