Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dibenzo[b,d]furan-4-yldiphenylphosphine oxide.
CATO supplies Dibenzo[b,d]furan-4-yldiphenylphosphine oxide (CAS 1268162-33-9), a certified reference material (molecular formula C24H17O2P, MW 368.36 g/mol) for analytical method development and quality control.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, Dibenzo[b,d]furan-4-yldiphenylphosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.36 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.
CATO manufactures Dibenzo[b,d]furan-4-yldiphenylphosphine oxide 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.
