3-Diphenylphosphinyl-9-(4'-diphenylphosphinylphenyl)carbazole CAS 1226860-68-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Diphenylphosphinyl-9-(4'-diphenylphosphinylphenyl)carbazole.

CATO supplies 3-Diphenylphosphinyl-9-(4'-diphenylphosphinylphenyl)carbazole (CAS 1226860-68-9), a certified reference material (molecular formula C42H31NO2P2, MW 643.65 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, 3-Diphenylphosphinyl-9-(4'-diphenylphosphinylphenyl)carbazole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 643.65 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3-Diphenylphosphinyl-9-(4'-diphenylphosphinylphenyl)carbazole 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.
