Denatonium, usually available as denatonium benzoate (under trade names such as Bitrex or Aversion) and as denatonium saccharide, is the most bitter compound known to date.

The TASF reagent or tris(dimethylamino)sulfonium difluorotrimethylsilicate is a reagent in organic chemistry with structural formula [((CH₃)₂N)₃S]⁺[F₂Si(CH₃)₃]^-. It is an anhydrous source of fluoride and is used to cleave silyl ether protective groups. Many other fluoride reagents are known, but few are truly anhydrous, because of the extraordinary basicity of "naked" F^-. In TASF, the fluoride is masked as an adduct with the weak Lewis acid trimethylsilylfluoride (FSi(CH₃)₃). The sulfonium cation ((CH₃)₂N)₃S⁺ is unusually non-electrophilic due to the electron-donating properties of the three (CH₃)₂N substituents.

Rabeprazole is an antiulcer drug in the class of proton pump inhibitors. It was developed by Eisai Co. and is marketed by Janssen-Cilag as rabeprazole sodium under the brand names Aciphex and Pariet.

Deltamethrin is a pyrethroid ester insecticide.

Pantoprazole (brand names Pantopan in Italy; Protium; Protonix; Pantozol; Pantor; Pantoloc; Astropan; Controloc; Pantecta;Inipomp) is a proton pump inhibitor drug used for short-term treatment of erosion and ulceration of the esophagus caused by gastroesophageal reflux disease. Initial treatment is generally of eight weeks' duration, after which another eight week course of treatment may be considered if necessary. It can be used as a maintenance therapy for long term use after initial response is obtained. This medication may affect the results of certain lab tests (e.g. false positive urine screen for tetrahydrocannabinal-THC). It is recommended you make sure laboratory personnel and your doctor know you are using this drug.

Ferulic acid is an organic compound that is an abundant phenolic phytochemical found in plant cell walls. It is a derivative of trans-cinnamic acid. As a component of lignin, ferulic acid is a precursor in the manufacture of other aromatic compounds.

Verbenone is a natural organic compound classified as a terpene which plays an important role in the control of the Southern pine bark beetle.

Propionaldehyde or propanal is the organic compound with the formula CH₃CH₂CHO. It is a saturate 3-carbon aldehyde and is a structural isomer of acetone. It is a colourless liquid with a slightly irritating, fruity odour.

Nizatidine is a histamine H₂-receptor antagonist that inhibits stomach acid production, and commonly used in the treatment of peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD). It was developed by Eli Lilly and is marketed under the trade names Tazac and Axid.

Famotidine (INN) () is a histamine H₂-receptor antagonist that inhibits stomach acid production, and is commonly used in the treatment of peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD/GORD). It is commonly marketed by J&J/Merck under the trade names Pepcidine and Pepcid.
