Manufacturing Quality Control of Fast Red ITR
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Mass loss after high-temperature ashing; residue weight reflects inorganic impurities. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration using silver nitrate and chloride-selective electrode; endpoint detected by potential change. |
| Sulfate Impurity | Gravimetric Analysis with BaCl2 | Precipitation as barium sulfate followed by filtration, drying, and weighing. |
| Iron Content | Colorimetric Method with 1,10-Phenanthroline | Formation of orange-red ferroin complex measured spectrophotometrically at 510 nm. |
| pH of Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a 1% w/v aqueous suspension. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine size distribution in dispersed suspension. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary method. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral molecules in solution. |
