What is para-Imazamethabenz?

Plain description, key identifiers and synonyms

Rac-6-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)-p-toluic acid is a racemate comprising equimolar amounts of the R- and S- enantiomers of 6-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)-p-toluic acid. It is the minor component of the herbicide imazamethabenz. It contains a 6-[(4R)-4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl]-p-toluic acid and a 6-[(4S)-4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl]-p-toluic acid.
