Manufacturing Quality Control of 4-Methylbenzophenone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Appearance | Visual Inspection | Assessment of physical state and color against a white background under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated thermometer and standard reference materials. |
| Loss on Drying | Gravimetric Method (105 C, 2 h) | Measurement of mass loss after drying under specified temperature and time to assess volatile impurities and moisture content. |
| Residue on Ignition | Sulfated Ash Method | Conversion of organic matter to sulfate ash by controlled combustion, followed by gravimetric quantification of inorganic residue. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals (as Pb) after wet digestion, using air-acetylene flame and appropriate hollow cathode lamps. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of chlorinated by-products (e.g., chlorobenzophenones) using electron ionization and selective ion monitoring. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and gradient elution. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with sample in anhydrous methanol-based reagent. |
| Acid Value | Acid-Base Titration (NaOH, phenolphthalein) | Neutralization of acidic impurities with standardized sodium hydroxide solution; endpoint detected by color change. |
| UV Absorbance (Solution in Ethanol) | UV-Vis Spectrophotometry | Measurement of absorbance at specified wavelengths (e.g., 254 nm) to detect conjugated impurities or degradation products. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Determination of mass per unit volume for free-flowing powder using standardized tapping and weighing procedures. |
