Manufacturing Quality Control of 2,4-DINITROPHENYLACETIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion; measures absorbance of ground-state atoms at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantifies chloride relative to calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid-to-liquid phase change occurs. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of crystalline solid against defined specifications under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate particle size distribution based on Mie or Fraunhofer theory. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of trace volatile organic impurities using gas chromatography coupled with mass spectrometric detection. |
