1,10-Phenanthroline(Cat No.:R047653)is a heterocyclic aromatic compound composed of three fused rings, including two nitrogen atoms positioned at the 1 and 10 locations. Known for its strong chelating ability, it forms stable complexes with a wide range of metal ions, making it a valuable ligand in coordination chemistry and catalysis. It is widely used in redox chemistry, metal detection assays, and as a stabilizer in polymer chemistry. In biochemical research, 1,10-phenanthroline is often employed as a metalloproteinase inhibitor due to its high affinity for divalent metal ions like Fe²⁺ and Zn²⁺.
