Manufacturing Quality Control of H-TYR(BZL)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 220 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., L-tyrosine, O-benzyl-L-tyrosine methyl ester) using gradient HPLC with UV detection. |
| Optical Rotation | [alpha]D measurement | Measures specific rotation at 20 C using sodium D-line to confirm chiral integrity and enantiomeric purity. |
| Residual Solvents | GC-FID | Quantifies residual solvents (e.g., methanol, ethyl acetate, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via volumetric or coulometric titration using iodine-based redox reaction in anhydrous pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after ignition at 600 C following sulfuric acid treatment. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines pH of a 1% w/v aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in suspension using Mie scattering theory and laser diffraction analysis. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Microbial Limits | Membrane Filtration and Plate Count | Assesses total aerobic microbial count and absence of specified pathogens (E. coli, Salmonella) per USP <61> and <62>. |
