2,2«-dichloro-4,4«-dinitro­bibenz­yl CAS 105222-71-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2«-dichloro-4,4«-dinitro­bibenz­yl.

2,2«-dichloro-4,4«-dinitro­bibenz­yl (CAS 105222-71-7) is a high-purity analytical reference standard with the molecular formula C14H10Cl2N2O4 and a molecular weight of 341.15 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2,2«-dichloro-4,4«-dinitro­bibenz­yl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2,2«-dichloro-4,4«-dinitro­bibenz­yl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
