Chemical Structure
Description
4-(tert-Butyl)-4,5-dihydro-3H-dinaphtho[2,1-c:1',2'-e]phosphepine (CAS 515811-32-2), molecular formula C26H25P and molecular weight 368.45 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a polycyclic aromatic system, 4-(tert-Butyl)-4,5-dihydro-3H-dinaphtho[2,1-c:1',2'-e]phosphepine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.45 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.
