Denatonium, usually available as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, Bitrex or Aversion) and as denatonium saccharide (BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. Description: Denatonium in humans is recognized by eight distinct bitter taste receptors: TAS2R4, TAS2R8, TAS2R10, TAS2R39, TAS2R43, TAS2R16, TAS2R46, TAS2R47, with TAS2R47 being by far the most sensitive to the compound. 6: Pulkkinen V, Manson ML, Säfholm J, Adner M, Dahlén SE. 2002-2018, Drug, The bitter chemical compound, Basic, Hydrophobic, Ionizable, N-Benzyl-2-(2,6-dimethylanilino)-N,N-diethyl-2-oxoethan-1-aminium benzoate, Benzenemethanaminium, N-[2-[(2,6-dimethylphenyl)amino]-2-oxoethyl]-N,N-diethyl- benzoate (1:1), Benzyl diethyl ((2,6-xylylcarbamoyl)methyl) ammonium benzoate, Benzenemethanaminium, N-[2-[(2,6-dimethylphenyl)amino]-2-oxoethyl]-N,N-diethyl-, benzoate, Ammonium, benzyldiethyl[(2,6-xylylcarbamoyl)methyl]-, benzoate, Benzenemethanaminium, N-[2-[(2,6-dimethylphenyl)amino]-2-oxoethyl]-N,N-diethyl-, benzoate (1:1).
Denatonium, also known as Bitrex, is a bitterant (or bitter agonist). If the solution appears cloudy or dirty, discard as it may have been contaminated.
For example, it can be used in a dilute solution to brush on the fingernails of people who are compulsive fingernail-biters. Denatonium benzoate is a substance that’s put into household, garden and automotive products to ensure that if a child or animal ever tried to swallow it, they would spit it straight out before they could be poisoned.

Denatonium benzoate has many other applications. They are used as aversive agents (bitterants) to prevent inappropriate ingestion. Exposure to the pure compound may cause respiratory discomfort, but only people working with the substance directly are likely to encounter this problem.  Do not substitute other forms of saccharin or use any other sweetener. Stimulation of insulin secretion by denatonium, one of the most bitter-tasting substances known.
PubMed PMID: 9133381. In one line of his experiments, Barnes added a single benzoyl group (benzoic acid with a hydrogen removed: C6H5COO−) to a nitrogen atom in lidocaine. This is expected to be enough to complete about 30‒70 qualitative fit tests. C28H34N2O3. 8: Jung HY, Kim W, Yoo DY, Nam SM, Kim JW, Choi JH, Yoon YS, Kim HY, Hwang IK.
