2 2'-Bipyridine CAS 366-18-7

1. 2,2'-Bipyridine CAS 366-18-7 is a versatile bidentate chelating ligand widely used in coordination chemistry to form stable complexes with transition metals for applications in catalysis, materials science, and photochemistry .
2. 2 2'-Bipyridine serves as a key building block in the synthesis of ruthenium and iridium complexes for use in organic light-emitting diodes (OLEDs), solar cells, and as photosensitizers in photodynamic therapy .
3. 2,2'-Bipyridine is employed as a ligand in cross-coupling reactions, including Suzuki-Miyaura and Heck reactions, and as a redox mediator in electrochemical applications .
4. Researchers utilize 2 2'-Bipyridine as a reference standard in analytical chemistry, as a metal ion chelator in biochemical studies, and as a building block for supramolecular assemblies and metal-organic frameworks (MOFs) .

1. 2,2'-Bipyridine must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; recommended storage at room temperature in a cool, dark place .
2. 2 2'-Bipyridine is classified with GHS hazard statements H301 (Toxic if swallowed), H311 (Toxic in contact with skin), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Danger" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition; wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when 2,2'-Bipyridine is released .
2. Collect 2 2'-Bipyridine by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. 2,2'-Bipyridine is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as 2 2'-Bipyridine may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 2,2'-Bipyridine due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
