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 .

Leucocyanidin reductase (LCR) uses 2,3-trans-3,4-cis-leucocyanidin to produce (+)-catechin and is the first enzyme in the proanthocyanidin (PA) specific pathway. Its activity has been measured in leaves, flowers, and seeds of the legumes Medicago sativa , Lotus japonicus , Lotus uliginosus , Hedysarum sulfurescens , and Robinia pseudoacacia ...
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]
3-Methylcatechol is an organic compound with the formula CH 3 C 6 H 3 (OH) 2 A white solid, it is one of the isomers of methylbenzenediol. Being structurally related to lignans , it is contributes to the aerosol generate by combustion of wood.
They are also categorized as methyl phenols. Cresols commonly occur as either solids or liquids because their melting points are generally close to room temperature. Like other types of phenols, they are slowly oxidized by exposure to air , and the resulting impurities often give the samples a yellow to brownish red tint.
