Manufacturing Quality Control of 2,4-Diaminoanisole sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies the main component by titrating with standardized H2SO4 or NaOH based on its amine functionality. |
| Moisture Content | Karl Fischer Titration | Measures water content via iodometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Loss on Drying | Gravimetric Analysis | Determines volatile matter by measuring mass loss after drying at specified temperature and time. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Detects trace metal impurities (e.g., Pb, Fe, Cu) by measuring absorption of element-specific UV-Vis radiation. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and ignition. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode in a defined aqueous suspension. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness/browning against APHA color standards using 430 nm absorbance or visual matching. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by weighing residue after high-temperature incineration. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Iron Content | 1,10-Phenanthroline Spectrophotometry | Forms orange-red complex with Fe2+; quantified by absorbance at ~510 nm. |
| Bulk Density | Volumetric Gravimetry | Calculates mass per unit volume using standardized cylinder and tapping procedure per USP <616>. |
