Manufacturing Quality Control of R-(-)-5-(2-Amino-propyl)-2-methoxy-benzenesulfonamide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible impurities under natural light or standard illumination. |
| Identification | Infrared Spectroscopy (IR) | Compare the infrared spectrum of the sample with that of a reference standard to confirm the consistency of functional groups and molecular structure. |
| Nuclear Magnetic Resonance Spectroscopy (¹H-NMR or ¹³C-NMR) | Analyze characteristic peaks of the compound through hydrogen or carbon spectra to confirm its chemical structure and stereochemistry (e.g., R-configuration). | |
| Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Separate enantiomers using a chiral column to confirm the enantiomeric purity and configuration (R-(-)-isomer) of the main component. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Quantify the content of the main component using a reversed-phase column (e.g., C18) and UV detector, calculating purity by external or internal standard method. |
| UV-Visible Spectrophotometry (UV-Vis) | Measure absorbance at the maximum absorption wavelength and calculate concentration using a standard curve, suitable for rapid quantification of high-purity samples. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate impurity peaks using gradient elution, calculate impurity content based on relative retention time and peak area, evaluating purity and stability. |
| Moisture | Karl Fischer Titration | Determine water content using the reaction between iodine and sulfur dioxide in an anhydrous environment, suitable for precise detection of trace moisture. |
| Residual Solvents | Gas Chromatography (GC) | Detected according to ICH guidelines, to identify organic solvents (such as methanol, ethanol, dichloromethane, etc.) that may remain during production. |
| Melting Point | Melting Point Apparatus Method | Determine the melting temperature range using the capillary tube method, used to preliminarily assess purity and consistency. |
| Specific Rotation | Polarimeter Method | Measure the optical rotation of the solution under sodium D line (589 nm), calculate specific rotation to verify chirality (R-(-)-configuration). |
| Particle Size Distribution | Laser Diffraction Analysis | Used for solid drug substances, to evaluate particle size distribution, affecting dissolution and formulation performance. |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Determine the content of harmful elements such as lead, cadmium, mercury, and arsenic, meeting pharmacopoeia or ICH Q3D elemental impurity limits. |
| Microbial Limit | Microbial Limit Test Method | Includes total aerobic bacterial count, total mold and yeast count, and control organisms (e.g., Escherichia coli, Salmonella), ensuring sterility and safety. |
