| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key structural building blocks in the synthesis of drug molecules | Employed in organic synthesis reactions—including Suzuki and Stille cross-coupling—to construct complex drug molecular frameworks |
| Materials Science | Raw material for synthesizing functional materials | Used to prepare organic semiconductor or fluorescent materials with tailored optoelectronic properties |
| Agrochemical Intermediates | Synthesis of active pharmaceutical ingredients (APIs) for agrochemicals | Applied in the synthesis of biologically active agrochemicals, such as insecticides and fungicides |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, toluene, methanol) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using plasma excitation and atomic emission detection. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity-based quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfur Content | Combustion IC | Oxidative combustion followed by ion chromatographic detection of sulfate formed from organic sulfur compounds. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the bulk sample against established reference standards under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Weighing of inorganic residue remaining after high-temperature ashing of the sample in a platinum crucible. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH solution to quantify acidic impurities (e.g., residual acetic acid) using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral impurities or degradation products in solution at specified concentration and wavelength. |
