| Polymers | Synthesis of functional polymers or additives | Polymerization or crosslinking to introduce specific functional groups |
Manufacturing Quality Control of 1072-67-9
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase column with a UV detector (e.g., 210–254 nm) to quantify the main component and assess sample purity. The mobile phase commonly uses a methanol/water or acetonitrile/salt buffer system. |
| Content Determination | HPLC external standard method or titration | The external standard method quantifies using a calibration curve established with standard samples; acid-base titration is suitable for amino compounds with obvious acidity or basicity, using HCl or NaOH for titration. |
| Related Substances/Impurity Analysis | HPLC Gradient Elution Method | Gradient elution procedure is used to separate and detect synthetic by-products or degradation impurities, typically combined with a DAD detector for peak purity and structural assistance. |
| Moisture Determination | Karl Fischer Titration Method | Determines trace moisture content in the sample using coulometric or volumetric methods, ensuring the product's dryness meets pharmacopoeia or industrial standards. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with FID or MS detection to analyze residual organic solvents (e.g., methanol, ethanol, dichloromethane), in compliance with ICH Q3C guidelines. |
| Melting Point Determination | Capillary Melting Point Apparatus Method | Measures the temperature at which a compound transitions from solid to liquid, used as a physical constant for identification and initial purity assessment. |
| Structure Confirmation | Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS) | IR confirms functional group characteristic absorption; ¹H/¹³C NMR provides hydrogen and carbon skeleton information; MS determines molecular weight and fragment structure. Combined use confirms chemical structure. |
| Heavy Metal Detection | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detected according to pharmacopoeia methods (e.g., USP <231> or ICH Q3D), determining the limit of harmful metal elements such as lead, cadmium, mercury, and arsenic. |
| Drying Loss | Oven Drying Method | Dries the sample to constant weight at a specific temperature (e.g., 105°C), calculating the percentage of mass loss to evaluate volatile substances or adsorbed water content. |
| Appearance and Physical Properties | Visual Inspection and Physical Description | Observes color, crystal form, odor, etc. The appearance should be white to off-white crystalline powder, free of visible foreign matter. |
