Description

4,5-Difluorobenzo(A)Pyrene is a high-purity, polycyclic aromatic hydrocarbon (PAH) derivative specifically functionalized with fluorine atoms at the 4 and 5 positions. This fluorinated analog is a critical advanced intermediate and reference standard for research and development in analytical chemistry and materials science. It is primarily utilized by pharmaceutical research organizations, environmental testing laboratories, and specialty chemical manufacturers.

Application

• Analytical Reference Standard: Used as a certified standard for the calibration and validation of analytical instruments (e.g., HPLC, GC-MS) in environmental pollutant analysis and food safety testing.
• Pharmaceutical Research: Serves as a key synthetic intermediate or a metabolite analog in the study of drug metabolism, toxicity, and the development of fluorescence-based probes.
• Environmental Science: Employed in research focused on the detection, fate, and transport of fluorinated polycyclic aromatic hydrocarbons (F-PAHs) in ecosystems.
• Material Science Research: Investigated as a building block for organic semiconductors, luminescent materials, and other advanced organic electronic components due to its fluorinated PAH structure.
• Toxicology Studies: Used as a model compound to understand the biological activity and carcinogenic potential of fluorinated derivatives of benzo[a]pyrene.
• Chemical Synthesis: Acts as a specialized precursor for the synthesis of more complex fluorinated organic molecules for various research applications.
