![]() ![]() Adulterants are various substances which are mixed into drugs as fillers by dealers, thus increasing the amount that they can sell. Freebasing also refers to the process of freeing the active ingredients of a drug from its adulterants with which, in the slang term, it has been "cut". ![]() When used as a verb, it refers to smoking freebase cocaine, crack cocaine, freebase heroin or more rarely freebase PCP. If impurities contain amines, or other pendant groups with similar pH profiles, however, they are likely to follow the desired compound through both stages of the freebasing process. This is what is often informally done by narcotic drug users. Most of the non-amine compounds which crossed over into the aqueous previously will remain there, because a change of pH is unlikely to affect its phase preference.Ĭonversely, it is possible to take amine in the salt form, freebase it into the organic layer, and extract it back into water by acidification. The amine compound will now be uncharged and become resolubilized into the organic layer, away from the aqueous. ![]() The second step is to extract the amine compound back into the organic layer by treating the water with base ("freebasing"). Many compounds without amines will remain in the organic phase, although some compounds may cross into the aqueous phase as well. Since it is protonated, and organic solvents are less likely to solubilize charged compounds, the amine migrates to the aqueous phase. First, the amine compound is extracted into a water away from organic solvents by the addition of acid. The process of freebasing is often a key procedure during the workup chemical reaction that produces an amine. Freebase amines are often found as hydrochloride salt, although other negative counterions are found, such as acetate, oxalate, bromide, et cetera. ![]() The salt form is the neutral amine compound with an additional proton, which is positively charged, plus a negative counterion. Most alkaloids are unstable and corrosive in their freebase form, and thus are usually stored in salt form. Freebase refers to the standalone basic form of an amine, usually an alkaloid natural product, as opposed to its water-soluble salt form. ![]()
