AP-237:
https://en.wikipedia.org/wiki/AP-237Getting to try some of this actually, soon. Should be interesting. Meant to be equipotent with morphine and highly reinforcing, as well as being quite to very selective (going from summary, not read the SAR papers on this family of piperazine opioids. yet) for mu-opioid receptors over DOR and KOR (delta and kappa) and presumably ORL1/nociceptin.
And silver nitrate is clutching at straws these days, the last I read, mainly it used, a long, long time ago, in stick or pencil form, for cauterizing ulcers and such. They do use silver as a dressing, impregnated in some kind of fabric. I have a few actually left from when I hurt my foot. And I plan on simply digesting the entire dressing using nitric acid to form AgNO3 then precipitating it as silver chloride using a chloride salt, such as table salt, in a salt metathesis reaction, whereby essentially the result is two salts being mixed in solution and the anions and cations swapping over with each other. Often using kinetics to drive the rxn to the right, such as 2AgNO3+2NaCl>NaNO3&AgCl2, sodium nitrate being very soluble indeed in water, whilst silver chloride is most insoluble and will precipitate out. Its also photosensitive, and indeed at one point used to be used for early photography processes by means of selectively exposing the view you want to outline in the light, turning silver halide salts into metallic silver.
The last I read of lunar caustic (as it used to be known in medicine) being used, it was in one of my books I was reading last night, one of a two volume set from a physician's treatise dating back from the 1700s. I have both volumes, in good condition. Great books, big heavy leatherbound tomes with ink-marbling decoration on a first front page and on the edges of the pages so it can be seen when the book is closed, on the sides of the page edges when they are all together. Got all sorts of little personal notes and recipes dating back from some previous owner of the books at the time they were actually being used, such as a recipe for cough syrup.
