| Research Sector | Photochemical Reagent | Employed in laboratory research as a triplet-state photosensitizer or quencher, leveraging its photochemical properties |
Manufacturing Quality Control of 4-Hydroxybenzophenone
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Scans the sample using infrared spectroscopy and compares characteristic absorption peaks (e.g., phenolic hydroxyl, carbonyl groups) with reference standard spectra to confirm structural consistency. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with UV detection (typically at 254 nm or 280 nm), quantifying the main component based on retention time and peak area. |
| Purity and Impurity Testing | High-Performance Liquid Chromatography (HPLC) | Builds upon content determination; evaluates total organic impurities and individual impurity limits using area normalization or impurity correction factor methods. |
| Residual Solvents | Gas Chromatography (GC) | Follows pharmacopeial methods (e.g., Chinese Pharmacopoeia, USP) to detect residual organic solvents (e.g., methanol, ethanol, acetone) from manufacturing processes. |
| Moisture Content | Karl Fischer Titration | Accurately determines water content using either volumetric or coulometric Karl Fischer method, suitable for quality control requiring high sensitivity to moisture. |
| Melting Point | Melting Point Determination | Determines the melting temperature range using a melting point apparatus or capillary tube method; compared with the standard value (approximately 148–150°C) to assess purity. |
| Appearance | Visual Inspection | Observes physical characteristics such as color, state (e.g., white to off-white crystalline powder), and presence of visible foreign particles. |
| Solubility | Solubility Test | Tests solubility behavior in solvents such as water, ethanol, methanol, ethyl acetate, etc., ensuring compliance with specified solubility properties. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, detects trace heavy metals (e.g., lead, cadmium, mercury, arsenic); results must meet pharmaceutical or industrial safety limits. |
| Residue on Ignition | Residue on Ignition Test | Heats the sample to high temperature, then weighs the residue to assess inorganic impurity levels; commonly used in raw material quality control. |
