Chemical Structure

Diphenyl(trimethylsilyl)phosphine CAS 17154-34-6 chemical structure

Description

Diphenyl(trimethylsilyl)phosphine (CAS 17154-34-6) is a high-purity analytical reference standard with the molecular formula C15H31PSi and a molecular weight of 270.47 g/mol.

Structurally, Diphenyl(trimethylsilyl)phosphine (C15H31PSi) contains organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 270.47 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.

As a certified reference material (CRM), Diphenyl(trimethylsilyl)phosphine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
