Chemical Structure
Description
Diphenyl((trimethylsilyl)methyl)phosphine (C16H21PSi) contains organophosphorus functionality, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Diphenyl((trimethylsilyl)methyl)phosphine (CAS 4451-96-1), molecular formula C16H21PSi and molecular weight 272.40 g/mol, is a CATO reference standard with documented purity and traceability.
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)methyl)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.
