Picric acid converted it to acetylsalicylic acid, i.e., aspirin, to keep it from the Allies. See Great Phenol Plot. At the time, phenol was obtained from coal as a co-product of coke ovens and the manufacture of gas for gas lighting. Laclede Gas reports being asked to expand production of phenol (and toluene) to support the war effort. Both Monsanto and Dow Chemical undertook manufacture of synthetic phenol in 1915. Dow was the leading producer. Dow describes picric acid as “the main battlefield explosive used by the French. Large amounts [of phenol] also went to Japan, where it was made into picric
Chorismic acid and pyruvate. This enzyme catalyses the first step in ubiquinone biosynthesis in "Escherichia coli" and other Gram-negative bacteria. Chorismic acid Chorismic acid, more commonly known as its anionic form chorismate, is an important biochemical intermediate in plants and microorganisms. It is a precursor for: The name chorismic acid derives from a classical Greek word, "χωρίζω" meaning "to separate", because the compound plays a role as a branch-point in aromatic amino acid biosynthesis. Shikimate → shikimate-3-phosphate → 5-enolpyruvylshikimate-3-phosphate (5-O-(1-carboxyvinyl)-3-phosphoshikimate) Chorismate synthase is an enzyme that catalyzes the final chemical reaction 5-O-(1-carboxyvinyl)-3-phosphoshikimate → chorismate + phosphate. Chorismate is transformed into "para"-aminobenzoic acid
