| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates | Prepared via Grignard reagent reactions followed by downstream processing |
| Pesticides | Synthesis of pesticide intermediates | Applied in the synthesis of compounds with specific biological activity |
| Cosmetics | Formulation of skincare product ingredients | Used as active or auxiliary ingredient |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area against a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separation of R- and S-enantiomers on a chiral stationary phase; ee calculated from peak area ratio of enantiomers. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, ethyl acetate) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically to generate endpoint current or volume change. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anion in aqueous extract; quantified via external calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Sample incineration at 500-600 C followed by sulfuric acid treatment and final ash weighing to determine inorganic residue content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range where solid transforms to liquid under controlled heating rate. |
| Optical Rotation | [alpha]D Measurement | Specific rotation measured at 589 nm (Na D-line) using a polarimeter; indicates chiral purity and identity confirmation. |
| Related Substances | HPLC-UV (Forced Degradation) | Stability-indicating method with acidic, basic, oxidative, thermal, and photolytic stress testing to detect and quantify degradation products. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution in dry or wet dispersion. |
| Bulk and Tapped Density | ASTM D6393 | Gravimetric measurement of mass per unit volume before and after standardized mechanical tapping to assess powder flow and compaction behavior. |
