Manufacturing Quality Control of 3,5-Diiodo-L-tyrosine dihydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 280 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-iodo analogs, des-iodo tyrosine) using gradient HPLC-UV with suitable column and mobile phase. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions using anion-exchange column and suppressed conductivity detector. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled ashing at 700-800 C, expressed as percentage weight loss. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a defined aqueous suspension or solution using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using laser scattering to determine D10, D50, D90 values per ISO 13320. |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
| Iodine Content | Oxidimetric Titration | Quantification of total iodine via reduction to iodide followed by iodometric titration with standardized sodium thiosulfate solution. |
