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(2,2-dimethyl-6,6,7,7,8,8,8-heptafluoro-3,5-octanedionato)barium dihydrate.
Bis(2,2-dimethyl-6,6,7,7,8,8,8-heptafluoro-3,5-octanedionato)barium dihydrate (CAS 143457-82-3), molecular formula C20H20BaF14O4H2O and molecular weight 745.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(2,2-dimethyl-6,6,7,7,8,8,8-heptafluoro-3,5-octanedionato)barium dihydrate (C20H20BaF14O4H2O) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
