Manufacturing Quality Control of 2,2-Diphenylacetic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies 2,2-diphenylacetic acid by titration with standardized NaOH using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities (e.g., Pb, Cd, Hg) by measuring absorption of element-specific light wavelengths. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions using silver nitrate titrant and silver/silver chloride reference electrode. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition with sulfuric acid pretreatment. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance at 254 nm. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Identifies and quantifies residual solvents (e.g., toluene, methanol) using flame ionization detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard white background under controlled lighting. |
| pH of Aqueous Suspension | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension to assess acidic character and potential hydrolysis. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity and identity by measuring rotation of plane-polarized light in solution. |
