Catechol - Wikipedia
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.
Dihydroxybenzenes - Wikipedia
In organic chemistry, dihydroxybenzenes (benzenediols) are organic compounds in which two hydroxyl groups (−OH) are substituted onto a benzene ring (C6H6). These aromatic compounds are classed as phenols. There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta ...
17.1 Naming Alcohols and Phenols - Organic Chemistry - OpenStax
Alcohols are classified as primary (1°), secondary (2°), or tertiary (3°), depending on the number of organic groups bonded to the hydroxyl-bearing carbon. Simple alcohols are named in the IUPAC system as derivatives of the parent alkane, using the suffix - ol. RULE 1.
