1,7-Dimethyl-9H-fluorene, with the CAS number 442-66-0, is an organic compound belonging to the class of polycyclic aromatic hydrocarbons (PAHs). It features a fluorene backbone, which consists of a fused ring system comprising a phenyl group and a cyclopentane ring. The presence of two methyl groups at the 1 and 7 positions of the fluorene structure contributes to its unique chemical properties. This compound is typically characterized by its solid state at room temperature, exhibiting a white to pale yellow crystalline appearance. It is relatively insoluble in water but soluble in organic solvents such as benzene and toluene. 1,7-Dimethyl-9H-fluorene is of interest in various fields, including materials science and organic electronics, due to its potential applications in the development of organic semiconductors and light-emitting devices. Additionally, like other PAHs, it may pose environmental and health concerns, necessitating careful handling and assessment of its toxicity and environmental impact.

1,7-Dimethylfluorene

1,7-Dimethylfluorene is a molecule that has been shown to cause fluorescence when in crystalline form. Chemists have utilized this property to identify 1,7-dimethylfluorene in the presence of other molecules. Although 1,7-dimethylfluorene has not been extensively studied in crop plants, it has been found to increase yields and reduce toxins in some cases. This molecule is not resistant against herbicides such as zingiberol or gamma-terpinene and can be used as an attractant for insects. 1,7-Dimethylfluorene also encodes a synthase protein that assists in the production of plant hormones.
