Manufacturing Quality Control of 1-Methyl-3-nitrophthalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, toluene) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent where water reacts stoichiometrically; endpoint detected potentiometrically. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on element-specific atomic emission intensities in plasma. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; quantified using external calibration. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of residual inorganic salts after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue after heating at 600 C for 30 min in a platinum crucible. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution; indicates chiral purity if applicable. |
