Manufacturing Quality Control of 139481-69-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC with UV detection; reported as individual and total impurity percentages. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify specified organic solvents (e.g., methanol, ethyl acetate, toluene) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, As, Hg, Ni) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 600-800 C, expressed as percentage weight loss. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity and identity of the enantiomerically enriched compound. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, indicating crystallinity and purity. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry or wet dispersion by measuring angular variation in laser light scattering intensity. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic/basic degradation potential. |
