Manufacturing Quality Control of 4-cyano-3-nitrobenzoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-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, DMF) based on calibrated external standards. |
| 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 detection after acid digestion, measuring emission intensities of metals (e.g., Pb, Cd, Ni) at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on an ion-exchange column with suppressed conductivity detection, quantified against sodium chloride standards. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C after sulfuric acid treatment; residue weighed as inorganic sulfate 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 presence of foreign particles under controlled white light against established reference standards. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered laser light intensity as a function of angle to calculate volume-based particle size distribution. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using a calibrated glass electrode. |
| Organic Volatile Impurities (OVI) | GC-MS | Targeted and untargeted screening using gas chromatography coupled to mass spectrometry for structural identification and quantification. |
