For research and development scientists, the precise specifications of chemical reagents are fundamental to the success of their experiments. Trimethylsulfoxonium Iodide (CAS 1774-47-6) is a valuable reagent, and understanding its typical specifications is key to its effective utilization. This overview aims to guide R&D professionals on what to look for when sourcing this compound, whether for laboratory synthesis or pilot-scale testing.

The appearance of Trimethylsulfoxonium Iodide is consistently described as a white to light yellow crystalline powder. This physical characteristic is a primary indicator of product quality and consistency. Deviations from this expected appearance could suggest contamination or improper storage, prompting further investigation or rejection of the batch.

A critical specification for any chemical intermediate is its assay, which indicates the percentage purity of the desired compound. For Trimethylsulfoxonium Iodide, a high assay of ≥99% is typically required. This level of purity is crucial for many applications, especially in pharmaceutical synthesis, where even minor impurities can significantly affect reaction outcomes, yield, and the quality of the final product. Researchers should always verify the assay from the supplier's Certificate of Analysis (CoA).

Other important specifications often found on a CoA or TDS include Loss on Drying (typically ≤0.20%), indicating low moisture content, and Heavy Metal limits (≤20ppm), which are vital for applications sensitive to metal contamination. Residue on Ignition (≤0.20%) also points to the inorganic impurity level. These parameters collectively define the suitability of the Trimethylsulfoxonium Iodide for specific research purposes.

When sourcing Trimethylsulfoxonium Iodide, scientists should prioritize suppliers who provide comprehensive technical documentation and are responsive to inquiries regarding these specifications. Engaging with manufacturers who can offer technical support and detailed data sheets ensures that you are obtaining a reagent that meets your exact R&D requirements. Considering the availability from reputable suppliers, particularly those with a strong presence in the market, will facilitate your research endeavors.

By paying close attention to these chemical specifications, R&D scientists can confidently select and utilize Trimethylsulfoxonium Iodide, ensuring the reliability and reproducibility of their experimental results.
