4-Methylcatechol (4-methylbenzene-1,2-diol) Orcinol (5-methylbenzene-1,3-diol) Methoxyphenols — can be derived from benzenediols by O-methylation. Guaiacol (2-methoxyphenol, O-Methylcatechol) Mequinol (4-Methoxyphenol) Dimethoxybenzenes — can be derived from benzenediols by two rounds of O-methylation. Veratrole (1,2-Dimethoxybenzene) 1,3 ...
Benzene-1,3-diol is the name recommended by the International Union of Pure and Applied Chemistry (IUPAC) in its 1993 Recommendations for the Nomenclature of Organic Chemistry. [29] Resorcinol is so named because of its derivation from ammoniated resin gum, and for its relation to the chemical orcinol. [30]

By 1852, Erdmann realized that catechol was benzene with two oxygen atoms added to it; in 1867, August Kekulé realized that catechol was a diol of benzene, so by 1868, catechol was listed as pyrocatechol. [7] In 1879, the Journal of the Chemical Society recommended that catechol be called "catechol", and in the following year, it was listed as ...
tert-Butylbenzene can be produced by the treatment of benzene with isobutene [1] or by the reaction of benzene with tert-butyl chloride in presence of anhydrous aluminium chloride, [2] the latter is depicted below:
After exposure to 63 to 405 mg/m 3 of benzene for 1 to 5 hours, 51 to 87% was excreted in the urine as phenol over a period of 23 to 50 hours. In another human study, 30% of absorbed dermally applied benzene, which is primarily metabolized in the liver, was excreted as phenol in the urine.
