Manufacturing Quality Control of 2-Hydroxydiphenylmethane
| Test Item | Common Analytical Method | Method Summary |
|---|---|---|
| Purity (Active Ingredient Content) | High-Performance Liquid Chromatography (HPLC) | Use a C18 chromatographic column with methanol-water or acetonitrile-water as mobile phase. A UV detector (usually at 254 nm) is used for detection, and the active ingredient content is quantified using an external standard method or internal standard method, suitable for high-precision quantitative analysis. |
| Purity (Active Ingredient Content) | Gas Chromatography (GC) | Suitable for volatile samples. Use a capillary column (e.g., DB-5), FID detector, and determine the content by standard curve method. Thermal stability should be considered to avoid decomposition. |
| Impurity Profile Analysis | HPLC-UV / HPLC-MS | HPLC combined with UV or mass spectrometry detection can separate and identify structural analog impurities (such as unreacted phenol, benzyl chloride, dimers, etc.). Mass spectrometry provides molecular weight and fragment information for structural confirmation. |
| Melting Point | Melting Point Apparatus (Capillary Method) | Determine the melting point range according to the Chinese Pharmacopoeia or USP methods (literature value approximately 58–61°C), used for preliminary judgment of purity and crystal form consistency. |
| Moisture Content | Karl Fischer Titration | Use coulometric or volumetric methods to measure trace moisture in the sample. Suitable for moisture-sensitive APIs or intermediates, with precision down to ppm level. |
| Appearance and Color | Visual Inspection + Colorimeter | Observe whether the sample is white to light yellow crystals or powder. Use a colorimeter or color comparison method (e.g., APHA color) to evaluate the color, reflecting the degree of purification. |
| Heavy Metal Residue | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, use AAS or inductively coupled plasma mass spectrometry to determine heavy metal content such as Pb, Cd, Hg, As, complying with ICH Q3D limit requirements. |
| Residual Solvents | GC-MS / GC-FID | According to ICH Q3C standards, use headspace sampling GC method to detect residual solvents such as ethanol, acetone, toluene, dichloromethane. MS is used for qualitative analysis, and FID for quantitative analysis. |
| Infrared Spectrum (Structure Confirmation) | Fourier Transform Infrared Spectroscopy (FT-IR) | Obtain characteristic functional group absorption peaks (e.g., O-H stretching vibration at 3200–3600 cm⁻¹, aromatic C=C at 1500–1600 cm⁻¹, C-O at 1200 cm⁻¹), and compare with standard spectra to confirm structure. |
| Chloride / Inorganic Ions | Ion Chromatography (IC) | If chlorinated reagents (e.g., benzyl chloride) are used during synthesis, residual chloride ions can be detected using an anion exchange column and conductivity detector, offering high sensitivity. |
