| Organic Synthesis | Linker for preparing functional ligands (e.g., metal–organic frameworks, MOFs) | Coordinates with metal ions (e.g., Fe³⁺, Cr³⁺) to form porous crystalline materials used in gas adsorption or catalysis |
| Materials Science | Comonomer in liquid crystal polymers and high-performance polyesters | Integrated via melt condensation or interfacial polymerization to enhance polymer thermal stability and mechanical strength |
Manufacturing Quality Control of 2,3-dihydroxyterephthalic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and spectral matching support qualification. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in methanol-based reagent to determine water by stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic mass spectrometry for ultra-trace sensitivity. |
| Chloride Content | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection for quantitative chloride determination. |
| Sulfate Content | Ion Chromatography | Same principle as chloride analysis, optimized for sulfate elution and detection via conductivity. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to assess inorganic ash content. |
| pH of Aqueous Solution | Potentiometric Titration | Measurement of pH using calibrated glass electrode in a saturated aqueous suspension or dilute solution. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established visual standards under controlled lighting. |
| Bulk Density | Tap Density Measurement | Mass per unit volume determined by measuring the volume of a known mass after standardized tapping in a graduated cylinder. |
