Diphenyl(spiro[fluorene-9,9'-xanthen]-2-yl)phosphine oxide CAS 1346002-80-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 532.57 g/mol gives Diphenyl(spiro[fluorene-9,9'-xanthen]-2-yl)phosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diphenyl(spiro[fluorene-9,9'-xanthen]-2-yl)phosphine oxide (CAS 1346002-80-9) is a high-purity analytical reference standard with the molecular formula C37H25O2P and a molecular weight of 532.57 g/mol.

Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Diphenyl(spiro[fluorene-9,9'-xanthen]-2-yl)phosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 532.57 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.
