Chemical Structure

1,4-Dihydroxy-2-nitroanthracene-9,10-dione CAS 23743-40-0 chemical structure

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-Dihydroxy-2-nitroanthracene-9,10-dione.

1,4-Dihydroxy-2-nitroanthracene-9,10-dione (CAS 23743-40-0) is a high-purity analytical reference standard with the molecular formula C14H7NO6 and a molecular weight of 285.21 g/mol.

1,4-Dihydroxy-2-nitroanthracene-9,10-dione (C14H7NO6) contains a nitrogen-containing heterocyclic scaffold, 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.
