Description

The occurrence of Poly(oxy-1,2-ethanediyl), .alpha.-[2-[3,6-bis(diethylamino)xanthylium-9-yl]benzoyl]-.omega.-hydroxy-, bis[2-[2-[4,5-dihydro-3-methyl-5-(oxo-.kappa.O)-1-phenyl-1H-pyrazol-4-yl]diazenyl-.kappa.N1]benzoato(2-)-.kappa.O]chromate(1-) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Poly(oxy-1,2-ethanediyl), .alpha.-[2-[3,6-bis(diethylamino)xanthylium-9-yl]benzoyl]-.omega.-hydroxy-, bis[2-[2-[4,5-dihydro-3-methyl-5-(oxo-.kappa.O)-1-phenyl-1H-pyrazol-4-yl]diazenyl-.kappa.N1]benzoato(2-)-.kappa.O]chromate(1-) (CAS 103651-08-7), molecular formula C30H35N2O4C17H12N4O3Cr and molecular weight 859.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Poly(oxy-1,2-ethanediyl), .alpha.-[2-[3,6-bis(diethylamino)xanthylium-9-yl]benzoyl]-.omega.-hydroxy-, bis[2-[2-[4,5-dihydro-3-methyl-5-(oxo-.kappa.O)-1-phenyl-1H-pyrazol-4-yl]diazenyl-.kappa.N1]benzoato(2-)-.kappa.O]chromate(1-) (C30H35N2O4C17H12N4O3Cr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
