Manufacturing Quality Control of 3-Hydroxypicolinic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine in methanol to determine water content by stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for high sensitivity and selectivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride calibration standards. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of residual inorganic salts as sulfate ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using capillary tube method per USP <741>, observing solid-to-liquid phase change range. |
| Optical Rotation | [alpha]D Measurement | Specific rotation determination using sodium D-line (589 nm) in solution, indicating chiral purity and absence of racemization. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Electrode-based measurement of hydrogen ion activity in a defined aqueous suspension or solution. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to derive volume-based particle size distribution. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery of viable aerobic microorganisms from dissolved sample via filtration, followed by incubation on soybean-casein digest agar. |
