Chemical Structure
Description
CATO supplies 1,2,5,6-Tetrahydroxyanthracene-9,10-dione (CAS 632-77-9), a certified reference material (molecular formula C14H8O6, MW 272.21 g/mol) for analytical method development and quality control.
Structurally, 1,2,5,6-Tetrahydroxyanthracene-9,10-dione (C14H8O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 272.21 g/mol, it falls into the medium-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.
