Chemical Structure
Description
The occurrence of Trioctylphosphine sulfide, CYTOP? 505 is closely related to sulfur-containing functionality, organophosphorus functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Trioctylphosphine sulfide, CYTOP? 505 (CAS 2551-53-3), a certified reference material (molecular formula C24H51PS, MW 402.70 g/mol) for analytical method development and quality control.
Structurally, Trioctylphosphine sulfide, CYTOP? 505 (C24H51PS) contains sulfur-containing functionality, 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 402.70 g/mol, it falls into the moderately-high-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), Trioctylphosphine sulfide, CYTOP? 505 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.
