Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyltri(thiophen-2-yl)phosphonium iodide.
Methyltri(thiophen-2-yl)phosphonium iodide (CAS 27127-37-3) is a high-purity analytical reference standard with the molecular formula C13H12PS3I and a molecular weight of 422.29 g/mol.
Methyltri(thiophen-2-yl)phosphonium iodide (C13H12PS3I) contains sulfur-containing functionality, organophosphorus functionality, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyltri(thiophen-2-yl)phosphonium iodide 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.
