Chemical Structure
Description
The occurrence of Tri(2-thienyl)phosphine is closely related to sulfur-containing functionality, organophosphorus functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tri(2-thienyl)phosphine (CAS 24171-89-9) is a high-purity analytical reference standard with the molecular formula C12H9PS3 and a molecular weight of 280.37 g/mol.
Tri(2-thienyl)phosphine (C12H9PS3) contains sulfur-containing functionality, 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 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), Tri(2-thienyl)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.
