Manufacturing Quality Control of Methyl 5-nitroisophthalate
| 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 relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, toluene) against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantitative analysis after acid digestion; detection based on characteristic atomic emission spectra intensities. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantified via calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C following 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 under controlled white light against defined criteria for color, clarity, and presence of foreign particles. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution in suspension. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light by chiral molecules in solution at specified concentration, path length, and wavelength (589 nm). |
