Manufacturing Quality Control of 98349-25-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~270 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV/DAD | Separation and detection of structurally related impurities (e.g., des-fluoro analogs, hydrolysis products) using gradient HPLC with diode-array detection for spectral confirmation. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual ethyl acetate, ethanol, DMF, or dichloromethane per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other toxic metals via inductively coupled plasma mass spectrometry after acid digestion. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in anhydrous methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by ignition at 600–750 °C followed by precise weighing of residual inorganic matter. |
| Optical Rotation | [α]D Measurement | Specific rotation measurement at 20 °C using sodium D-line (589 nm) to confirm chiral integrity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size distribution (D10, D50, D90) using laser scattering principles per ISO 13320. |
| Microbial Limits | Membrane Filtration & Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
| pH of Aqueous Suspension | pH Potentiometry | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode to assess acidic/basic degradation propensity. |
