Manufacturing Quality Control of Basic Violet 1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies methyl violet concentration based on absorbance at characteristic wavelength (e.g., ~580 nm) using Beer-Lambert law. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Measures mass loss after drying at specified temperature to determine volatile content including moisture and solvents. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine, based on stoichiometric reaction with water. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorption of specific atomic spectral lines. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures inorganic residue remaining after high-temperature ignition following sulfuric acid treatment. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration monitored by silver ion-selective electrode. |
| Sulfate Impurity | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a defined aqueous suspension using calibrated pH electrode. |
| Solubility in Water | Visual Observation / Filtration Test | Assesses complete dissolution in specified volume of water at controlled temperature and time. |
| Color Value (E1%1cm at 580 nm) | UV-Vis Spectrophotometry | Reports specific absorbance normalized to 1% concentration and 1 cm path length for batch-to-batch color consistency. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents (e.g., methanol, acetone) using flame ionization detection. |
| Microbial Contamination | Membrane Filtration / Plate Count | Detects aerobic mesophilic microorganisms by filtration, culture on nutrient agar, and colony enumeration. |
