Manufacturing Quality Control of Methyl 3-nitro-4-hydroxybenzoate
| 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 relative to reference standards or threshold reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone) based on calibrated external standard curves. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on atomic emission intensities at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantified using chloride standard calibration. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final ash weighing to determine inorganic residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid transforms to liquid. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and identity. |
| pH of Aqueous Suspension | pH Meter | Electrochemical measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) at 25 C. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to calculate volume-based particle size distribution in dispersed sample. |
| Residue on Ignition | Gravimetric Analysis | Weight loss determination after heating at 600 C for 30 min; reports non-volatile inorganic residue as percentage. |
