1-(2,5-Dibromophenyl)-2-phenyldiazene CAS 2528-87-2 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-(2,5-Dibromophenyl)-2-phenyldiazene.

1-(2,5-Dibromophenyl)-2-phenyldiazene (CAS 2528-87-2), molecular formula C12H8Br2N2 and molecular weight 340.01 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(2,5-Dibromophenyl)-2-phenyldiazene (C12H8Br2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 340.01 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.
