Manufacturing Quality Control of 3-Hydroxyphenylphosphinyl-propanoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection and comparison to retention times/spectra of known impurities. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750-800 C to combust organic matter, then weighing inorganic residue as sulfate ash. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on ion-exchange column with suppressed conductivity detection; chloride quantified against calibration curve. |
| pH of Aqueous Solution | Potentiometric Measurement | Measurement of hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using controlled heating and visual observation. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution in a defined cell path length and concentration. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Weight loss measured under controlled nitrogen atmosphere from 25 C to 105 C over 2 hours. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection for residual solvents per ICH Q3C guidelines. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. scattering angle to calculate volume-based particle size distribution. |
