Manufacturing Quality Control of 4-Amino-3,5-difluoropyridine
| 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 254 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 according to ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to determine water content based on stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-MS | Quantitative determination of trace metal impurities (e.g., Pb, Cd, Ni, Fe) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measurement after incineration at 600-700 C followed by sulfuric acid treatment and ignition to constant weight. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to assess chiral purity (if applicable) or identity confirmation. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine particle size distribution in dry or dispersed powder samples. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using a calibrated pH electrode system. |
| Microbial Limits | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms via filtration, membrane transfer to culture media, and colony counting after incubation. |
