Manufacturing Quality Control of 1,1,1-Tris(4-hydroxyphenyl)ethane
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column and a UV detector (e.g., 280 nm) to determine the purity of the main component by external standard method or area normalization. The mobile phase is typically methanol/water or acetonitrile/water system. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyze hydrogen atoms and carbon atoms in the molecule using ¹H-NMR and ¹³C-NMR, including chemical shifts and coupling constants, to confirm whether the compound structure is correct. |
| Impurity Content | HPLC or LC-MS | Use high-sensitivity HPLC combined with mass spectrometry (LC-MS) to identify and quantify relevant impurities (such as synthetic by-products or degradation products), ensuring compliance with pharmacopoeia or enterprise standards. |
| Loss on Drying | Oven Drying Method (GB/T 6284 or similar) | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, and calculate the percentage of mass loss to assess moisture and volatile substance content. |
| Melting Point Determination | Capillary Melting Point Apparatus Method | Use a digital melting point apparatus to measure the melting temperature range of the sample to judge crystallinity and purity consistency. |
| Residual Solvents | Gas Chromatography (GC-FID or GC-MS) | According to ICH Q3C guidelines, use headspace injection or direct injection GC methods to detect residual organic solvents (e.g., toluene, ethanol) from the synthesis process. |
| Heavy Metal Content | Atomic Absorption Spectrophotometry (AAS) or ICP-MS | After wet digestion, use AAS or ICP-MS to measure the content of harmful metal elements such as lead, cadmium, mercury, and arsenic, ensuring compliance with safety limits. |
| Appearance and Color | Visual Inspection | Observe the color, form (white to off-white crystalline powder), and presence of foreign matter under natural light or standard light source. |
| pH Value (if dissolved in solution) | pH Meter Measurement | Dissolve the sample in a specified solvent (e.g., water or ethanol-water solution), and measure its acidity/alkalinity using a calibrated pH meter to assess stability or applicability. |
| UV Absorption Characteristics | UV-Visible Spectrophotometry (UV-Vis) | Scan the wavelength range from 200–400 nm to confirm the position of the maximum absorption peak and absorbance, which can assist in identification and semi-quantitative assessment of purity. |
