Manufacturing Quality Control of Dimethyl 5-nitroisophthalate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observing the color, state, and presence of visible impurities under natural light or standard light sources. Suitable for assessing product purity and process stability. |
| Purity/Main Component Content | HPLC (High-Performance Liquid Chromatography) | Using a reverse-phase C18 column and a UV detector (typically around 254 nm), the content of the target compound is determined by external standard method or area normalization method. It has high accuracy and is suitable for quantitative analysis. |
| Structural Confirmation | NMR (Nuclear Magnetic Resonance Spectroscopy) | Using 1H-NMR and 13C-NMR to confirm the structure of the compound, identifying functional group positions and molecular symmetry, used for authenticity verification and impurity structure inference. |
| Impurity Analysis | GC-MS (Gas Chromatography-Mass Spectrometry) or LC-MS (Liquid Chromatography-Mass Spectrometry) | Used for identification and quantification of trace organic impurities (such as unreacted raw materials, by-products, etc.), with high sensitivity and structural analysis capability. |
| Moisture Content | Karl Fischer Titration | Measuring moisture content by using the quantitative reaction between iodine and sulfur dioxide in pyridine/alcohol solution. Suitable for low moisture detection at the ppm level. |
| Melting Point | Melting Point Determination (Capillary Method) | Determining the melting temperature range of solid samples using a melting point apparatus to assess purity and crystallinity consistency; pure substances typically have sharp melting points. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH guidelines, using headspace-GC method to detect residual organic solvents (such as methanol, dichloromethane, etc.) from the production process, ensuring compliance with safety limits. |
| Heavy Metals | AAS (Atomic Absorption Spectroscopy) or ICP-MS (Inductively Coupled Plasma Mass Spectrometry) | Determining the residual levels of heavy metals such as lead, cadmium, mercury, and arsenic in the sample, ensuring product safety, especially for quality control of pharmaceutical intermediates. |
| Residue on Ignition (Sulfuric Ash) | Gravimetric Method | Heating the sample to high temperatures, adding sulfuric acid for carbonization, then high-temperature ashing, and weighing the residue to evaluate the total amount of inorganic impurities. |
