Sodium 1,4-dihydroxy-9,10-dioxo-3-(4-sulfonatophenoxy)-9,10-dihydroanthracene-2-sulfonate CAS 94094-64-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 1,4-dihydroxy-9,10-dioxo-3-(4-sulfonatophenoxy)-9,10-dihydroanthracene-2-sulfonate.

Sodium 1,4-dihydroxy-9,10-dioxo-3-(4-sulfonatophenoxy)-9,10-dihydroanthracene-2-sulfonate (CAS 94094-64-1), molecular formula C20H10O11S2Na and molecular weight 513.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Sodium 1,4-dihydroxy-9,10-dioxo-3-(4-sulfonatophenoxy)-9,10-dihydroanthracene-2-sulfonate (C20H10O11S2Na) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 513.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
