Catechol (/ ˈkætɪtʃɒl / or / ˈkætɪkɒl /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C6H4(OH)2. It is the ortho isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts.

The catechol ring is a mere 6-carbon phenyl ring. 3,4-dihydroxybenzene, to be nerdishly precise. What makes it catechol is the presence of the exciting hydroxyl groups at the 3 and 4 position. Otherwise, its just boring old phenol. These two hydroxyl groups are what enables the catechol ring to be effective

2015年6月30日 · Catecholamines are based on the catechol ring, which is a phenol with hydroxyl groups at the 3 and 4 position. To this is added an ethylamine tail, which produces phenylethylamine.

A catechol is an unsaturated six-carbon ring (phenolic group) with two hydroxyl groups attached to adjacent carbons (dihydroxyphenol) (see Figure 3-1). Attachment of the catechol ring to a side chain with an amine group characterizes a catecholamine.

Catecholamines are catechols, which are chemicals that have adjacent hydroxyl groups on a benzene ring. Catechol itself does not exist in the human body, but compounds that contain catechol as part of their molecular structure are called catechols.

2015年6月30日 · Dopamine is the prototype catecholamine. It is naked and undecorated, a pure catechol ring attached to a pure ethylamine string. There are no additional groups to confuse its simple elegance. It lacks a beta-carbon group, so it is a weak agonist of both beta and alpha.

2004年7月3日 · Catechol is found to bind as a monoanion in agreement with experiments, while dioxygen is found to replace the water ligand. A spin-transition from the initial septet to a quintet state prepares the system for formation of a bridging peroxide with the catechol substrate.
