Manufacturing Quality Control of Solvent Green 5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at characteristic wavelength (~620–640 nm). |
| Loss on Drying (LOD) | Gravimetric (105 °C, 2 h) | Mass loss measured after drying under standardized temperature and time to determine volatile content including residual solvents and moisture. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of toxic metals by plasma excitation and optical emission spectroscopy following acid digestion. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on stoichiometric reaction between iodine and water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric (550 °C) | Mass of non-volatile inorganic residue remaining after high-temperature ashing, indicating inorganic impurities. |
| Related Substances | HPLC-DAD | Separation and detection of structurally similar impurities (e.g., intermediates, isomers, degradants) using diode-array detection for spectral confirmation. |
| pH (1% aqueous suspension) | pH Meter | Measurement of hydrogen ion activity in a standardized aqueous dispersion, reflecting acidic/basic impurities or hydrolysis products. |
| Solvent Residues (e.g., DMF, methanol) | GC-FID | Quantitative analysis of residual organic solvents via gas chromatographic separation and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determination of size distribution in dispersed phase using angular dependence of laser light scattering. |
| Color Strength (Relative Absorbance) | UV-Vis Spectrophotometry | Comparison of absorbance at λmax (≈630 nm) against a reference batch in standardized solvent (e.g., ethanol/DMF), normalized per unit concentration. |
| Chloride Content | Ion Chromatography (IC) | Separation and conductivity-based quantification of chloride ions after aqueous extraction and filtration. |
| Ash Content | Gravimetric (550 °C) | Mass of inorganic residue after complete combustion, used as indicator of inorganic salt contamination. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after controlled tapping, relevant for handling and formulation consistency. |
| Microbial Contamination | Membrane Filtration + Culture | Enumeration of viable aerobic microorganisms following filtration, membrane transfer to nutrient media, and incubation per pharmacopeial guidelines (if applicable). |
