orange crystalline powder
9-Fluorenone-1-carboxylic acid was used in preparation of (E)- and (Z)-isomers of twisted 1,1′-dibromobifluorenylidene.
9-Fluorenone-1-carboxylic Acid is an intermediate in synthesizing Fluoren-1-ol (F462450), a metabolite of the PAH micropollutant Fluorene (F462002) with potential mutagenic effects. It is used as biomarkers to evaluate exposure to PAHs and environmental tobacco smoke in general population.
9-Fluorenone-1-carboxylic acid is formed as an intermediate during four-ring polycyclic aromatic hydrocarbon fluoranthene degradation by Pseudomonas alcaligenes strain PA-10.
