Methyl P-Toluenesulfonate, commonly known as Methyl Tosylate, is an organic sulfonate ester mainly used as a methylating agent in chemical synthesis. It is useful in reactions where a methyl group needs to be introduced into selected organic molecules. Its CAS number is 80-48-8.

ChemicalBull supports B2B buyers with COA, MSDS, TDS, purity details, packing information and commercial quotations. Buyers can share their required purity, quantity, application and delivery location for suitable supply information.


Overview of Methyl P-Toluenesulfonate

Methyl P-Toluenesulfonate is an organic compound. It is also known as Methyl 4-Methylbenzenesulfonate, Methyl Tosylate and Methyl Toluene-4-Sulfonate.

The molecule contains a methyl group attached to a p-toluenesulfonate group. This structure makes the methyl group reactive toward suitable nucleophiles, allowing Methyl P-Toluenesulfonate to work as a methylating reagent in organic synthesis.

Its main value is as an intermediate or reagent rather than as a finished product. It can be used in multi-step synthesis routes for pharmaceutical, fine chemical and specialty organic compounds. Product purity, moisture and impurity profile should be confirmed through the batch-specific Certificate of Analysis.


Applications of Methyl P-Toluenesulfonate

Pharmaceutical Intermediate Synthesis

Methyl P-Toluenesulfonate is used as a methylating reagent in selected pharmaceutical synthesis routes.

It can transfer a methyl group to suitable oxygen-, nitrogen- or sulfur-containing compounds, helping manufacturers prepare more complex pharmaceutical intermediates. Its use as a methylating agent in pharmaceutical and chemical synthesis is well established.

The required purity depends on the downstream reaction and impurity limits of the final intermediate.

Fine Chemical Manufacturing

Methyl Tosylate is used in fine chemical synthesis where controlled methylation is required. It may be used to modify phenols, amines, alcohols and other reactive organic molecules.

This makes it useful in multi-step synthesis routes for high-value intermediates and specialty compounds.

Agrochemical Intermediate Production

The product may be used in selected agrochemical intermediate synthesis where methylation is required during the production route.

Methyl P-Toluenesulfonate itself is not a ready-to-use agrochemical. It is mainly an upstream synthesis reagent or intermediate used in controlled chemical manufacturing.

Methylation Reactions

The main chemical function of Methyl P-Toluenesulfonate is methyl transfer.

It is used where manufacturers need to introduce a methyl group into a suitable organic molecule. It can react with selected nucleophiles under controlled conditions to form methylated products.

Reaction conditions, dosage and compatibility depend on the target molecule and production process.

Specialty Organic Synthesis

Methyl P-Toluenesulfonate can be used as a reagent in the manufacture of specialty organic compounds.

Its reactive sulfonate ester structure makes it useful in processes where controlled alkylation or methylation is required.

Research and Process Development

The product may also be used in industrial process development for evaluating methylation routes and improving reaction efficiency.

It is suitable for controlled chemical synthesis environments where purity and consistent reagent quality are important.
