CATO supplies 2,9-Di(pyridin-4-yl)anthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-1,3,8,10(2H,9H)-tetraone (CAS 136847-29-5), a certified reference material (molecular formula C34H16N4O4, MW 544.52 g/mol) for analytical method development and quality control.
Structurally, 2,9-Di(pyridin-4-yl)anthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-1,3,8,10(2H,9H)-tetraone (C34H16N4O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 29.0, corresponding to approximately 29 ring(s) or double-bond equivalent(s). With a molecular weight of 544.52 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.
