Manufacturing Quality Control of NSI-189
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at optimal wavelength, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV/DAD or UPLC-MS | Separation and identification/quantification of impurities based on retention time, UV spectra, and/or mass fragmentation patterns relative to the main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents according to ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with sample moisture. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic detection at sub-pptr levels. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using suppressed conductivity detection with standardized calibration. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration at 700–800 °C. |
| Optical Rotation | Polarimetry | Determination of specific rotation using sodium D-line light to assess chiral purity and enantiomeric identity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis detecting solid-to-liquid phase change via controlled heating and visual observation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine volumetric particle size distribution. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
