Manufacturing Quality Control of Tetraphenyl dipropyleneglycol diphosphite
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color and physical state (e.g., white to light yellow crystals or powder), checking for foreign matter, caking, or other physical abnormalities. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column with methanol/water or acetonitrile/water as the mobile phase, and a UV detector (e.g., 210–254 nm) to quantify the purity of the main component. |
| Assay | HPLC with External or Internal Standard Method | Compare with reference standard; calculate the mass fraction of the target compound based on peak area to ensure compliance with specifications (e.g., ≥98.0%). |
| Melting Point | Capillary Melting Point Method | Determine the melting temperature range using a digital melting point apparatus to assess purity and consistency of crystal structure (typical range approximately 120–130°C). |
| Moisture Content | Karl Fischer Titration | Use volumetric or coulometric method to determine trace moisture levels, ensuring product stability (typically required ≤0.5%). |
| Volatile Matter | Thermogravimetric Analysis (TGA) or Loss on Drying | Heat the sample at a specified temperature (e.g., 105°C), measure weight loss to evaluate the content of volatile impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After acid digestion of the sample, determine residual levels of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with RoHS or pharmacopoeial limits. |
| Organic Impurities | GC-MS or HPLC-DAD | Identify and quantify synthesis by-products or degradation products using gas chromatography-mass spectrometry or high-performance liquid chromatography with diode array detection. |
| Phosphorus Content | Spectrophotometry (Molybdenum Blue Method) or ICP-OES | Determine total phosphorus content via colorimetric reaction or inductively coupled plasma optical emission spectroscopy to verify molecular structure integrity. |
| Thermal Stability | Differential Scanning Calorimetry (DSC) | Analyze endothermic/exothermic behavior during heating to evaluate decomposition temperature and suitability for processing. |
