Manufacturing Quality Control of Sodium 3-nitrobenzenesulphonate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase column with mobile phases such as methanol/water or acetonitrile/buffer salt, and UV detection (e.g., 254 nm) for quantification of the main component's purity. |
| Content Determination | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Leverages the characteristic absorption of 3-nitrobenzenesulfonate sodium at a specific wavelength (around 380 nm), quantifying its concentration via standard curve method. |
| Moisture Content | Karl Fischer Titration | Determines trace moisture content using coulometric or volumetric methods, suitable for hygroscopic organic salts. |
| Residue on Ignition (Inorganic Impurities) | Gravimetric Analysis (High-Temperature Incineration) | Sample is ignited at high temperature (e.g., 600–800°C) until constant weight; the residue mass is measured to calculate total inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After acid digestion, trace elements such as lead, cadmium, mercury, and arsenic are determined, ensuring compliance with pharmacopeial or industrial safety standards. |
| pH Value | pH Meter Measurement | A solution of specified concentration (e.g., 1%) is prepared and its acidity/alkalinity is directly measured using a calibrated pH meter, reflecting product acid-base stability. |
| Appearance and Color | Visual Comparison (Colorimetry) | Inspects solid color (should be pale yellow to yellow crystalline powder) and compares it with standard reference solutions to detect abnormal discoloration. |
| Drying Loss | Drying Loss Method | Dried under specified conditions (e.g., 105°C) under vacuum or atmospheric pressure until constant weight; the percentage loss due to volatile substances is calculated. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | Utilizes gradient elution to separate the main peak from potential impurity peaks; impurity levels are calculated by area normalization or external standard method. |
| Melting Point | Capillary Melting Point Method | Determined using a digital melting point apparatus, providing the melting range as an initial indicator of compound purity and structural consistency. |
