Chemical Structure
Description
The occurrence of ((Trans-2-hydroxycyclohexyl)methyl)diphenylphosphine oxide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
((Trans-2-hydroxycyclohexyl)methyl)diphenylphosphine oxide (CAS 89358-63-4), molecular formula C19H23O2P and molecular weight 314.36 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, ((Trans-2-hydroxycyclohexyl)methyl)diphenylphosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
