Chemical Structure
Description
The occurrence of Chlorotris(triphenylphosphine)copper is closely related to a salt form, organophosphorus functionality, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chlorotris(triphenylphosphine)copper (CAS 15709-76-9), molecular formula C18H15ClCuP and molecular weight 361.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, Chlorotris(triphenylphosphine)copper is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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), Chlorotris(triphenylphosphine)copper 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.
