Chemical Structure

Tetramethylphosphoniumiodide CAS 993-11-3 chemical structure

Description

Tetramethylphosphoniumiodide (CAS 993-11-3), molecular formula IC4H12P and molecular weight 218.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, iodine substitution, Tetramethylphosphoniumiodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Tetramethylphosphoniumiodide 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.
