Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Dicyclohexyl(6,7,9,10-tetrahydrodibenzo[h,j][1,4,7]trioxacycloundecin-1-yl)phosphine (CAS 1256169-98-8) is a high-purity analytical reference standard with the molecular formula C28H37O3P and a molecular weight of 452.57 g/mol.
Owing to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, Dicyclohexyl(6,7,9,10-tetrahydrodibenzo[h,j][1,4,7]trioxacycloundecin-1-yl)phosphine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.57 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.
