9,10-Dioxo-9,10-dihydroanthracene-1-sulfonyl chloride CAS 4025-69-8

Description

9,10-Dioxo-9,10-dihydroanthracene-1-sulfonyl chloride (CAS 4025-69-8) is a high-purity analytical reference standard with the molecular formula C14H7ClO4S and a molecular weight of 306.72 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 9,10-Dioxo-9,10-dihydroanthracene-1-sulfonyl chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
