Manufacturing Quality Control of 689293-69-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, THF, DMF) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residues after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Particle Size Distribution | Laser Diffraction | Measurement of dry or wet dispersed particles via light scattering pattern analysis to determine D10, D50, D90 values. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under controlled temperature and vacuum to determine volatile content including residual solvents and moisture. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic/basic impurity profile. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
