Manufacturing Quality Control of 3,5-Dibromo-L-tyrosine
| 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-brominated isomers, des-bromo tyrosine, bromination by-products) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., methanol, ethyl acetate, dichloromethane) per ICH Q3C. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (Pb, Cd, Hg, As) after acid digestion, achieving sub-ppb sensitivity per USP <233>. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Optical Rotation | [α]D | Polarimetric measurement at 589 nm (sodium D-line) to confirm chiral integrity and enantiomeric purity relative to L-tyrosine reference. |
| Residue on Ignition | Gravimetric Analysis | Ignition at 700–800 °C followed by weighing of inorganic residue to assess inorganic ash content per USP <281>. |
| pH (1% aqueous suspension) | pH Meter | Electrochemical measurement of hydrogen ion activity in a saturated aqueous suspension to verify acid-base behavior consistent with amino acid structure. |
