Description General description trans-3-(3-Pyridyl)acrylic acid, a bifunctional ligand with both hard and soft coordination sites, is mainly used in constructing heterometallic complexes. Application trans-3-(3-Pyridyl)acrylic acid has been used as an organic linker to connect d and f block metals to form a 3D heterometallic coordination polymer with luminescence property. It may also be used in the synthesis of ethyl trans-3-(3-pyridyl)acrylate via esterification. Packaging 5, 25, 250 g in glass bottle
