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 1,5-Diiodoanthracene-9,10-dione.
1,5-Diiodoanthracene-9,10-dione (CAS 3311-73-7), molecular formula C14H6I2O2 and molecular weight 460.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,5-Diiodoanthracene-9,10-dione (C14H6I2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 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 460.01 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
