Dibenzo[b,j][4,7]phenanthroline CAS 223-00-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Dibenzo[b,j][4,7]phenanthroline (CAS 223-00-7), molecular formula C20H12N2 and molecular weight 280.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dibenzo[b,j][4,7]phenanthroline (C20H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 280.32 g/mol, it falls into the medium-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).

CATO manufactures Dibenzo[b,j][4,7]phenanthroline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
