Manufacturing Quality Control of Tetramethylammonium bromide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Tetramethylammonium Bromide) | Acid-Base Titration with NaOH | Quantifies active ingredient by back-titration after hydrolysis to methylamine and subsequent acid titration. |
| Water Content | Karl Fischer Titration | Measures water via iodine-sulfur dioxide redox reaction in methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies Cl- anions using ion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metals after wet digestion and atomic absorption at characteristic wavelength. |
| Iron Impurity | ICP-OES | Quantifies Fe by plasma excitation and emission intensity measurement at specific spectral line. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Determines volatile content by mass loss after heating at specified temperature and time. |
| Bromide Content | Potentiometric Titration with AgNO3 | Quantifies Br- via argentometric titration using silver nitrate and silver indicator electrode. |
