Manufacturing Quality Control of Didodecyldimethylammonium bromide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with Sodium Hydroxide | Quantifies active ingredient by back-titration after reaction with excess standardized NaOH. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption of characteristic wavelength light. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities as mass remaining after high-temperature ashing. |
| Chloride Impurity | Silver Nitrate Titration | Detects chloride ions by precipitation titration with standardized AgNO3 solution using potassium chromate indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Surface Tension (0.1% solution) | Du Noüy Ring Method | Measures interfacial tension at air-water interface using force required to detach a platinum ring from solution surface. |
| Microbial Contamination | Plate Count Method | Quantifies viable aerobic microorganisms by colony formation on nutrient agar after serial dilution and incubation. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Separates and quantifies residual solvents or volatile organics using capillary column and flame ionization detection. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume by measuring weight of sample freely poured into standardized cylinder. |
