Industrial Applications of 2,2'-Bipyridine-4,4'-dicarboxylic acid
| Industry | Application | Process |
|---|---|---|
| Materials Science | Ligand for metal–organic frameworks (MOFs) | Used as an organic linker to self-assemble with metal ions (e.g., Zn²⁺, Cu²⁺) into porous crystalline materials via solvothermal synthesis |
| Electrochemistry | Coadsorbent or ligand in dye-sensitized solar cells (DSSCs) | Applied in conjunction with ruthenium-based dyes to enhance electron injection efficiency or tune energy levels, typically deposited onto TiO₂ electrodes by spin-coating or immersion |
| Analytical Chemistry | Fluorescent probe or colorimetric sensor for metal ions | Employed for metal ion detection (e.g., Fe²⁺) based on chelation-induced fluorescence quenching or color change, used in solution assays or test strip fabrication |
| Coordination Chemistry | Synthesis of functional coordination complexes (e.g., catalysts, molecular devices) | Complexed with transition metal ions (e.g., Ru, Re) to form photoactive or catalytically active centers, commonly prepared via solution-phase synthesis or immobilized on solid supports |
Manufacturing Quality Control of 2,2'-Bipyridine-4,4'-dicarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., mono-acid, unreacted 2,2'-bipyridine, oxidative by-products) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, methanol, toluene) by gas chromatography with flame ionization detection against calibrated standards. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Ni, Fe) via inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Chloride Content | Ion Chromatography (IC) | Quantification of chloride anion using suppressed conductivity detection after separation on an anion-exchange column. |
| Loss on Drying (LOD) | Gravimetric (105 °C, 2 h) | Mass loss measured after drying under standardized temperature and time conditions to determine volatile content including water and residual solvents. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs, indicating crystallinity and purity. |
| Residue on Ignition | Gravimetric (550 °C) | Mass of non-volatile inorganic residue remaining after high-temperature ashing, reflecting inorganic impurities or catalyst residues. |
| pH (1% aqueous suspension) | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension, indicating acidic character and potential hydrolysis products. |
| Particle Size Distribution | Laser Diffraction | Determination of size distribution by analyzing angular variation in laser light scattering from a dispersed sample in liquid medium. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical quantification of water via iodine generation and stoichiometric reaction with sample water in anhydrous methanol-based electrolyte. |
| Appearance | Visual Inspection | Assessment of physical form, color, and homogeneity against established reference standards under controlled lighting conditions. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light, confirming absence of chiral contaminants (though compound is achiral, detects enantiomeric impurities if present). |
