Manufacturing Quality Control of 3,5-Diiodo-L-thyronine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~225 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV/HRMS | Separation and identification of impurities (e.g., mono-iodinated analogs, des-iodo, or dehydro derivatives) via gradient HPLC coupled with UV and high-resolution mass spectrometry. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As) after acid digestion, achieving sub-ppt detection limits. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Optical Rotation | [α]D | Polarimetric measurement at 589 nm (Na D-line) in sodium hydroxide solution to confirm chiral integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Ignition at 700–800 °C followed by weighing of inorganic residue to assess inorganic ash content per USP <281>. |
| Particle Size Distribution | Laser Diffraction | Dry dispersion and light scattering analysis to determine D10, D50, D90 values relevant for dissolution and formulation performance. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
