Chemical Structure

phenylbis(4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)phosphine oxide CAS 1426143-77-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 662.72 g/mol gives phenylbis(4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)phosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies phenylbis(4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)phosphine oxide (CAS 1426143-77-2), a certified reference material (molecular formula C44H31N4OP, MW 662.72 g/mol) for analytical method development and quality control.

The molecular framework of phenylbis(4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)phosphine oxide (C44H31N4OP) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, 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 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), phenylbis(4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)phosphine oxide 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.
