Manufacturing Quality Control of 4,4'-Diaminobenzophenone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent, measuring endpoint potentiometrically. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range at which solid crystals transform to liquid under controlled heating. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible, then weighing the non-volatile inorganic residue after cooling. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Reaction with hydrogen sulfide under acidic conditions to form colored metal sulfides, compared visually or spectrophotometrically against lead standard. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column with conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by high-temperature ashing; residue weighed after cooling. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and detection of volatile organic impurities using capillary column and flame ionization detector. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally related impurities using HPLC with diode array detection and spectral library matching. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and against white/black background. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Bulk Density | Graduated Cylinder Method | Determination of mass per unit volume by gently pouring sample into a calibrated cylinder and measuring settled volume. |
