Ethyl Tosylate for Sale (ethylation agent)

Loptr - 15-7-2019 at 07:21

I just received a quantity of Ethyl 4-Toluenesulfonate ester from Thomas Scientific, and was wondering if there is any interest in purchasing any. It is an alkylation agent, with reactivity similar to ethyl iodide. The tosyl group is a great leaving group allowing the introduction of an ethyl group into a molecule. You might have read on this forum about the potential of methyl tosylate as a substitute for methyl iodide.

Preparation of methyl tosylate, safe methylating agent

I currently have 5kg on hand, and will be posting pictures shortly. It melted in transport and looks like a brown liquid in a bottle in the pics, but that is fine and expected. It will be a solid when you receive it.

I havent decided on a price, and am willing to accept trades. Make me an offer.

What's the source?

Also, I think "methylation agent" in your title is probably a typo.

Yeah, autocorrect typo.

Is there a chance of over alkylation like with methyl iodide? Will methyl tosylate di and Tri methylate amines the way methyl iodide will, and will ethyl tosylate mono ethylate amines like ethyl iodide would? I'm assuming that ethyl iodide would cause less overalkylation than methyl iodide would.
