CATO manufactures Tetramethyl Arsonium Iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Tetramethyl Arsonium Iodide (CAS 5814-20-0), a certified reference material (molecular formula C4H12AsI, MW 261.96 g/mol) for analytical method development and quality control.
Owing to iodine substitution, Tetramethyl Arsonium Iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.96 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.
