| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antibacterial drug intermediates | Used in Grignard reactions and oxidation reactions |
| Agrochemicals | Preparation of herbicidal active ingredients | Applied in alkylation reactions and substitution reactions |
| Materials | Production of high-performance polymer monomers | Employed in condensation reactions and polymerization reactions |
| Fine Fragrances & Flavors | Synthesis of fragrance compounds | Utilized in reduction reactions and esterification reactions |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component by separation on capillary column and flame ionization detection, using external standard calibration. |
| Related Substances | GC-MS | Identifies and quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | GC-FID with headspace sampling | Detects volatile organic solvents by equilibrium headspace gas analysis and chromatographic separation. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-OES | Determines trace metal contaminants (e.g., Pb, Cd, Hg) by plasma excitation and elemental emission intensity measurement. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration | Measures free acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against specified reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature combustion and weighing of residual residue. |
| Specific Optical Rotation | Polarimetry | Quantifies chiral impurity impact by measuring rotation angle of plane-polarized light through solution. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after controlled tapping to assess powder flow and handling characteristics. |
