       Ethyl tosylate data     

Google turns up nothing... anybody has any physical data on this one? Especially boiling/melting point and density...

Thanks in advance :)

[edit] Well, found some minimal info @ alfa-aesar... actually mp only, it is 32-34C ...

BTW CAS number is 80-40-0

Try searching for ethyl p-toluenesulfonate instead of ethyl tosylate.
