Catechol

Japanese: カテコール
Catechol

Pyrocatechol, 1,2-dihydroxybenzene. C 6 H 6 O 2 (110.11). It is obtained by dry distillation of catechu, but can also be synthesized by alkaline fusion of o -chlorophenol or demethylation of guaiacol. Colorless prismatic crystals. Melting point 104 °C, boiling point 245 °C. 1.344. K a 3.3×10 -10 (18 °C). Easily sublimed, soluble in water, alcohol, and ether. Easily oxidized, especially in alkaline solutions, which tend to discolor in air. Forms a redox system with o -quinone and acts as one of the electron transport systems in the body. Used as a photographic developing agent in combination with metol ( p -methylaminophenol). It is also used as an analytical reagent, as it forms complexes with metals in alkaline solutions. [CAS 120-80-9]
