Manufacturing Quality Control of ACID YELLOW 17
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic wavelength (e.g., ~425 nm) using molar absorptivity and Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol medium. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Measures non-volatile inorganic residue after high-temperature incineration of sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by measuring absorption of specific atomic resonance lines after acid digestion. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions via titration with silver nitrate using silver electrode to detect endpoint. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in standardized aqueous suspension using calibrated glass electrode. |
| Water Solubility | Gravimetric Filtration and Drying | Evaluates undissolved residue after dissolving sample in water, filtering, drying, and weighing. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection. |
| Sulfated Ash | Gravimetric Analysis (Ignition with H2SO4) | Measures ash content after sulfuric acid treatment to convert volatile metals to stable sulfates. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder in a standardized cylinder. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 700 C) | Quantifies non-volatile residue remaining after ignition at specified temperature per pharmacopeial standards. |
