4,5-Diphenyloxazole（Cat No.:L034095）is a heteroaromatic compound consisting of an oxazole ring substituted with phenyl groups at the 4 and 5 positions. Known for its strong fluorescence and photostability, it is commonly used as a fluorophore in biochemical assays, scintillation counting, and optoelectronic applications. The extended conjugation provided by the phenyl groups enhances its electron delocalization, resulting in favorable optical properties. It is also explored as a structural motif in medicinal chemistry, where the oxazole ring contributes to bioactivity and metabolic stability. Its rigidity and planarity make it ideal for molecular design and material science research.
