Procaine salt

  1. Aug 23, 2010 #1
    Hi all, I need some help!

    some info:

    Penicillic acid [CAS RN: 90-65-3]: an antibiotic substance produced by several species of Penicillium and Aspergillus

    Penicillin G
    : Used in medicine. It is used in the form of its stable salts (benzathine, potassium, procaine, and sodium)

    Penicillin G Procaine
    [CAS RN: 6130-64-9]: the procaine salt of penicillin G; Chemically designation is (2S,5R,6R)- 3,3-Dimethyl-7-oxo-6-(2-phenylacetamido)-4-thia-1-azabicyclo [3.2.0] heptane-2-carboxylic acid WITH 2-(Diethylamino)ethyl p-aminobenzoate (1:1)

    I have penicillin g as sodium salt and procaine, but have not and cant find penicillin g as procaine salt.

    Is there any way to revert from penicillin sodium salt to penicillic ACID and then to make solution with procaine to get the penicillin as procaine salt (not sodium)???

    How the salts should be transformed into acids?

    In the medical practice is used a solution containing only 1% procaine and penicillin g sodium, here the procaine salt's goal is just to be an anesthetic - to make the intramuscular injection free of pain, but what happens if we make a solution of for example 100% procaine (not 1%), what happens with the sodium salt, it's gonna be a mess of 50% procaine and 50% sodium salt or what?
