Cyclohexyldiphenylphosphine Oxide CAS 13689-20-8

Description

Compared with other compounds in its class, the molecular weight of 284.33 g/mol gives Cyclohexyldiphenylphosphine Oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cyclohexyldiphenylphosphine Oxide (CAS 13689-20-8), molecular formula C18H21OP and molecular weight 284.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Cyclohexyldiphenylphosphine Oxide (C18H21OP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 284.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Cyclohexyldiphenylphosphine Oxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
