Calone, a derivative of 4-methylcatechol, is known in the fragrance industry as "watermelon ketone" for its distinctive odor. [3]The brand of low-temperature coke used as a smokeless fuel Coalite obtains homocatechol from ammoniacal liquor by solvent extraction, distillation and crystallisation.
Catechol (/ ˈ k æ t ɪ tʃ ɒ l / or / ˈ k æ t ɪ k ɒ l /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2. It is the ortho isomer of the three isomeric benzenediols .

Piperonal can be prepared by the oxidative cleavage of isosafrole or by using a multistep sequence from catechol or 1,2-methylenedioxybenzene.Synthesis from the latter chemical is accomplished through a condensation reaction with glyoxylic acid followed by cleaving the resulting α-hydroxy acid with an oxidizing agent.
Melting point: 5.5 °C (41.9 °F; 278.6 K) Boiling point: ... Creosol reacts with hydrogen halides to give a catechol. See also. Vanillin, a related phenol;
C 6 H 4 O 2 BH + HC 2 R → C 6 H 4 O 2 B-CHCHR. The product is a precursor to the Suzuki reaction and is the only borane which stops at the alkene instead of reacting further to the alkane. [3] [4] Catecholborane may be used as a stereoselective reducing agent when converting β-hydroxy ketones to syn 1,3-diols.
4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. [1] TBC is available in the form of a solid crystal flake [ 2 ] and 85% solution in methanol [ 3 ] or water.
