Uses edit

Mercuric nitrate has been used in mercuration of ketones.[2] Mercuric nitrate was formerly used in carroting felt for hats.

Health information edit

Mercury compounds are highly toxic. The use of this compound by hatters and the subsequent mercury poisoning of said hatters is a common theory of where the phrase "mad as a hatter" came from.
