Manufacturing Quality Control of 40732-91-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using gradient HPLC-UV; individual impurities reported relative to main peak area. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, acetone, DMF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous medium. |
| Heavy Metals | ICP-OES | Measures total heavy metal content (Pb, Cd, Hg, As, etc.) after acid digestion by optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using suppressed conductivity detection after aqueous extraction. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode. |
| Loss on Drying | Gravimetric Thermogravimetry | Determines volatile content by measuring mass loss after drying at 105 C for 2 hours under vacuum or air. |
| Residue on Ignition | Gravimetric Ashing | Measures inorganic residue after incineration at 600-700 C for 30 minutes following USP <281>. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory and optical detection. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
