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 ((1,4-Phenylenebis(oxy))bis(4,1-phenylene))bis((4-fluorophenyl)methanone).
((1,4-Phenylenebis(oxy))bis(4,1-phenylene))bis((4-fluorophenyl)methanone) (CAS 93597-87-6), molecular formula C32H20F2O4 and molecular weight 506.50 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, ((1,4-Phenylenebis(oxy))bis(4,1-phenylene))bis((4-fluorophenyl)methanone) (C32H20F2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 506.50 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
