Description

(Methyl)Tri-4-Tolylphosphonium Iodide-D3,13C is a high-purity, isotopically labeled organophosphonium salt, specifically designed for advanced research and analytical applications. This compound is valued for its role as a critical reagent in mechanistic studies and as a stable isotope-labeled internal standard for precise quantification. It is primarily sought by researchers and process chemists in the pharmaceutical, agrochemical, and material science industries who require deuterium and carbon-13 labeled compounds for mass spectrometry, NMR spectroscopy, and reaction pathway elucidation.

Application

• Isotopic Tracer in Reaction Mechanism Studies: Used to investigate reaction pathways, kinetics, and intermediates in organic synthesis, particularly in Wittig and related ylide chemistry.
• Internal Standard for Mass Spectrometry (MS): Serves as a high-purity, isotopically labeled reference standard for the accurate quantification of related phosphonium compounds or their derivatives in complex matrices via LC-MS or GC-MS.
• NMR Spectroscopy: Employed as a probe in nuclear magnetic resonance studies due to its deuterium (D) and carbon-13 labels, aiding in structural analysis and dynamic process monitoring.
• Pharmaceutical Intermediate Synthesis: Acts as a specialized building block for the synthesis of deuterated or 13C-labeled active pharmaceutical ingredients (APIs) and their precursors.
• Material Science Research: Utilized in the development of novel labeled ionic liquids, catalysts, or functional materials where isotopic labeling is required for tracking or property modification.
• Agrochemical Research: Applied in the synthesis and metabolic studies of isotopically labeled pesticides or plant growth regulators.

Quality Control

Our (Methyl)Tri-4-Tolylphosphonium Iodide-D3,13C is manufactured under strict quality control protocols to ensure high isotopic purity and chemical integrity, essential for sensitive analytical applications. Each batch is characterized by advanced spectroscopic techniques including NMR and Mass Spectrometry to confirm isotopic enrichment and chemical structure. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic abundance, and identification data is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment and handled under inert atmosphere when necessary to prevent degradation.
