thumb|Oral solution bottle of dypirone in its packaging (Portuguese lettering) Metamizole or dipyrone (informally known as the "Mexican aspirin") is a painkiller, spasm reliever, and fever reliever drug. It is most commonly given by mouth or by intravenous infusion. It belongs to the ampyrone sulfonate family of medicines and was patented in 1922. Metamizole is marketed under various trade names. It was first used medically in Germany under the brand name "Novalgin", later becoming widely known in Slavic nations and India under the name "Analgin".

Pyranine is a hydrophilic, pH-sensitive fluorescent dye from the group of chemicals known as arylsulfonates. Pyranine is soluble in water and is used as a coloring agent, biological stain, optical detecting reagent, and pH indicator. Pyranine is also used in yellow highlighters to provide their characteristic fluorescence and bright yellow-green colour. It is also found in some types of soap.

Fluorosulfonate, in organic chemistry, is a functional group that has the chemical formula F-SO2-R, and typically is a very good leaving group. In organic chemistry, fluorosulfonate is different than fluorosulfate. In fluorosulfonates, sulfur atom is directly bonded to a non-oxygen atom such as carbon. In inorganic chemistry, fluorosulfonate is another term for fluorosulfate, the anion F-SO2-O−, the conjugate base of fluorosulfonic acid. They form a series of salts with metal and organic cations called fluorosulfates.

Methiodal is a pharmaceutical drug that was used as an iodinated contrast medium for X-ray imaging. Its uses included myelography (imaging of the spinal cord); for this use, cases of adhesive arachnoiditis have been reported, similar to those seen under the contrast medium iofendylate.

Solasulfone is an antileprotic drug developed from the parent compound sulphetrone. It was first described and evaluated in the 1930s and 1940s as an antibacterial agent for the treatment of tuberculosis and various other infections, and later found to be effective in the treatment of leprosy.

Stibophen is an anthelmintic originally developed by Bayer that is used as a treatment for schistosomiasis by intramuscular injection. It is classified as a trivalent antimony compound. Brand names include Fouadin/Fuadin (named in honor of Fuad I of Egypt, who had enthusiastically supported its research and development).

3,3′,3′′-Phosphanetriyltris(benzenesulfonic acid) trisodium salt (abbreviated TPPTS), is an organic compound that is also known as sodium triphenylphosphine trisulfonate. The compound has the formula P(C6H4SO3Na)3. This white solid is an unusual example of a water-soluble phosphine. Its complexes are also water-soluble. Its complex with rhodium is used in the industrial production of butyraldehyde.

chemical compound

ORG-21465 is a synthetic neuroactive steroid, with sedative effects resulting from its action as a GABAA receptor positive allosteric modulator. It is similar to related drugs such as ORG-20599, and was similarly developed as an improved alternative to other sedative steroids such as althesin and allopregnanolone, which despite its superior properties in some respects has not proved to offer enough advantages to be accepted into clinical use.
