Manufacturing Quality Control of 6360-07-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Acid Red 37 content) | UV-Vis Spectrophotometry | Quantification based on absorbance at characteristic wavelength (approx. 510 nm) using molar absorptivity and Beer-Lambert law. |
| Color Strength | UV-Vis Spectrophotometry | Comparison of absorbance of sample solution versus certified reference standard under standardized conditions. |
| pH of 1% Aqueous Solution | Potentiometric Titration | Measurement using calibrated pH electrode in a defined aqueous dispersion; reflects acidity/basicity of dye solution. |
| Water Solubility | Gravimetric Analysis | Dissolution in distilled water at specified temperature, followed by filtration and drying/residue weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total extractable heavy metals after acid digestion, measured at element-specific wavelengths. |
| Arsenic | ICP-OES | Determination after wet digestion and hydride generation or direct plasma analysis; detects trace As content. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 500-600 C to constant weight; residue represents inorganic sulfate impurities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration using silver nitrate and chloride-selective electrode; measures soluble chloride impurities. |
| Organic Impurities (Related Substances) | HPLC-UV | Separation on reversed-phase column followed by UV detection; identifies and quantifies structurally related dye impurities. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric determination of water content via iodine-sulfur dioxide reaction in anhydrous methanol. |
| Bulk Density | Tap Density Measurement | Mass per unit volume after standardized tapping; assesses powder flow and handling properties. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine size distribution profile of dispersed powder. |
