Industrial Applications of Alizarin Complexone
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Complexometric indicator in metal ion titrations for the determination of divalent metal ions such as calcium, magnesium, zinc, and copper | Forms a red complex with metal ions within pH 5.5–7.5; free indicator is violet-blue; endpoint detected by color change from red-violet to violet-blue |
| Environmental Monitoring | Determination of total hardness (calcium and magnesium ions) in water | EDTA titration method using alizarin complexone as a selective indicator to enhance endpoint sharpness |
| Clinical Testing | Quantitative analysis of calcium and magnesium in serum or urine | EDTA complexometric titration in a buffered system (e.g., acetic acid–sodium acetate), with endpoint determined by indicator color change |
Manufacturing Quality Control of Alizarin Complexone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies active ingredient concentration via absorbance at characteristic wavelength (e.g., 520 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. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Determines inorganic impurities by ignition of sample to constant weight and weighing residual ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content by atomization and absorption measurement at specific wavelengths. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures chloride ion concentration via precipitation titration using silver nitrate and silver electrode detection. |
| Sulfate Impurity | Gravimetric Analysis (BaSO4 Precipitation) | Determines sulfate content by precipitation as barium sulfate and weighing the dried precipitate. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated pH electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents based on retention time and flame ionization detection response. |
| Melting Point | Capillary Melting Point Determination | Identifies purity and identity by measuring temperature range at which solid transitions to liquid. |
| Solubility in Water | Visual Solubility Test | Evaluates complete dissolution in distilled water at specified temperature and concentration per pharmacopeial guidelines. |
| Related Substances | High Performance Liquid Chromatography (HPLC-UV) | Separates and quantifies structurally similar impurities using reversed-phase column and UV detection. |
| Appearance | Visual Inspection | Assesses physical characteristics (color, crystallinity, absence of foreign particles) against reference standard under controlled lighting. |
