Manufacturing Quality Control of BENZOYL LEUCO METHYLENE BLUE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantitative determination based on absorbance at characteristic wavelength (e.g., ~660 nm) using Beer-Lambert law with reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color against specification (colorless to pale yellow crystalline solid). |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Loss on Drying | Gravimetric Method (105 C, 2 h) | Measurement of mass loss after drying to assess volatile impurities and residual solvents. |
| Residue on Ignition | Sulfated Ash Gravimetry | Quantification of inorganic residue after high-temperature combustion of sample. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using conductivity detection after ion exchange. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantitative measurement of total heavy metals via flame or graphite furnace AAS after acid digestion. |
| Related Substances | HPLC with UV Detection | Separation and quantification of structurally related impurities using reversed-phase chromatography and UV detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in reaction with water. |
| pH of Solution (1% w/v) | pH Meter Measurement | Determination of aqueous solution acidity/basicity using calibrated pH electrode. |
| Solubility in Water | Qualitative Solubility Test | Observation of complete dissolution in specified volume of water at defined temperature. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light to confirm chiral integrity and identity (if applicable). |
