Mercuric Chloride, also known as Mercury(II) Chloride, Dichloromercury, Sublimate, and Mercury Bichloride, appears as white, odorless hygroscopic crystals or powder having the chemical formula HgCl2 or Cl2Hg. It is insoluble in water and highly toxic that is able to volatize slightly at ambient conditions and appreciably at 100 o C. Purified Grade, also known as Pure or Practical Grade, refers to those high-purity compounds that do not fulfil the ACS, the USP, or the FCC grade requirements.

Inactivation Of Influenza Virus By Mild Antiseptics
A number of antiseptics were tested for their inactivating effect upon the virus of influenza during a brief period of exposure. This was accomplished by preparing mixtures of the antiseptics and virus, allowing them to remain in contact for 3 minutes, diluting the mixtures to the point where they would not be toxic for chick embryos and then injecting the material into embryonated eggs. Survival of the embryos indicated inactivation of the virus. The following preparations were found to inactivate the virus in 3 minutes or less: phenol, 3%; tincture of iodine, U.S.P. XII, 0.1%; Lugol's solution, U.S.P. XII, 1%; mercuric chloride, 1:1000; potassium permanganate, 1:1000; copper sulfate, 1%; propylene glycol, 90%; liquor antisepticus, N.F. VII, 80%. Read more here.
