Question: Auguste Laurent discovered what aromatic organic compound with the molecular formula CHOH?
Context: Benzothiophene is an aromatic organic compound with a molecular formula CHS and an odor similar to naphthalene (mothballs).  It occurs naturally as a constituent of petroleum-related deposits such as lignite tar.  Benzothiophene has no household use.  It is used primarily in industry and research. Auguste Laurent (14 November 1807 – 15 April 1853) was a French chemist who helped in the founding of organic chemistry with his discoveries of anthracene, phthalic acid, and carbolic acid. Phenol, also known as carbolic acid, is an aromatic organic compound with the molecular formula CHOH.  It is a white crystalline solid that is volatile.  The molecule consists of a phenyl group (−CH) bonded to a hydroxyl group (−OH).  It is mildly acidic and requires careful handling due to its propensity to cause chemical burns. Benzoxazole is an aromatic organic compound with a molecular formula CHNO, a benzene-fused oxazole ring structure, and an odor similar to pyridine.  Although benzoxazole itself is of little practical value, many derivatives of benzoxazoles are commercially important. Gluconic acid is an organic compound with molecular formula CHO and condensed structural formula HOCH(CHOH)COOH.  It is one of the 16 stereoisomers of 2,3,4,5,6-pentahydroxyhexanoic acid. Piperidine is an organic compound with the molecular formula (CH)NH.  This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH–) and one amine bridge (–NH–).  It is a colorless liquid with an odor described as objectionable, and typical of amines. the name comes from the genus name "Piper", which is the Latin word for pepper.  Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids. 1-Decanol is a straight chain fatty alcohol with ten carbon atoms and the molecular formula CHOH.  It is a colorless to light yellow viscous liquid that is insoluble in water and has an aromatic odor.  The interfacial tension against water at 20 °C is 8.97 mN/m. 1-Naphthol, or α-naphthol, is a fluorescent organic compound with the formula CHOH.  It is a white solid.  It is an isomer of 2-naphthol differing by the location of the hydroxyl group on the naphthalene ring.  The naphthols are naphthalene homologues of phenol, with the hydroxyl group being more reactive than in the phenols.  Both isomers are soluble in simple alcohols, ethers, and chloroform.  They are precursors to a variety of useful compounds.  Naphthols (both 1 and 2 isomers) are used as biomarkers for livestock and humans exposed to polycyclic aromatic hydrocarbons. Cyclopropenone is an organic compound with molecular formula CHO consisting of a cyclopropene carbon framework with a ketone functional group.  It is a colorless, volatile liquid that boils near room temperature.  The chemical properties of the compound are dominated by the strong polarization of the carbonyl group, which gives a partial positive charge with aromatic stabilization on the ring and a partial negative charge on oxygen.  It is an aromatic compound. 1,2-Benzisoxazole is an aromatic organic compound with a molecular formula CHNO containing a benzene-fused isoxazole ring structure.  The compound itself has no common applications; however, functionalized benzisoxazoles and benzisoxazoyls have a variety of uses, including pharmaceutical drugs such as some antipsychotics (including risperidone, paliperidone, ocaperidone, and iloperidone) and the anticonvulsant zonisamide.
