Manufacturing Quality Control of 2,2'-Dimethyl-1,1'-biphenyl-4,4'-diamine dihydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies the main compound by titration with standardized NaOH after liberation of free base from salt form. |
| Water Content | Karl Fischer Titration | Measures water content via iodometric reaction where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 500-600 C and weighing the residual inorganic matter. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions using silver nitrate titrant with silver indicator electrode and reference electrode. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Hg, As) by plasma excitation and elemental emission spectroscopy. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection at 254 nm. |
| Organic Volatile Impurities | GC-FID | Identifies and quantifies residual solvents (e.g., methanol, acetone) using gas chromatography with flame ionization detection. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against defined standards. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of a defined aqueous suspension or solution using calibrated pH electrode. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after combustion with sulfuric acid treatment to convert metals to sulfates. |
| Bulk Density | USP <616> Tap Density Method | Determines mass per unit volume after mechanical tapping to assess flow and handling properties. |
