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 Bis(3,5-diiodosalicylato)copper.
Bis(3,5-diiodosalicylato)copper (CAS 14040-04-1), molecular formula C14H6CuI4O6 and molecular weight 841.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(3,5-diiodosalicylato)copper (C14H6CuI4O6) is characterized by a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
