Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Dicyclohexyl[9,10-dihydro-12-(2-methoxyphenyl)-9,10-ethenoanthracen-11-yl]phosphine (CAS 1166994-78-0), molecular formula C35H39OP and molecular weight 506.66 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dicyclohexyl[9,10-dihydro-12-(2-methoxyphenyl)-9,10-ethenoanthracen-11-yl]phosphine (C35H39OP) contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 506.66 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
