di-tert-butyl((2R,3R)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide (CAS 2545293-95-4) is a high-purity analytical reference standard with the molecular formula C25H36O3P2 and a molecular weight of 446.50 g/mol.
Structurally, di-tert-butyl((2R,3R)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide (C25H36O3P2) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 446.50 g/mol, it falls into the moderately-high-molecular-weight range. 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.
