Manufacturing Quality Control of O-ACETYL-L-TYROSINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard. |
| Chiral Purity | (S)-Enantiomeric Excess | Chiral HPLC with chiral stationary phase (e.g., Chirobiotic V or Whelk-O1), UV detection, comparison to (R) and (S) reference standards. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification by retention time matching and/or spiking. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection, using internal standard (e.g., dimethylformamide-d7) and USP <467> compliant method. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; measures total water content based on electrochemical reaction stoichiometry. |
| Heavy Metals | ICP-MS | Quantitative determination of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution; detection at sub-ppt levels. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride anion in aqueous solution after sample dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 500-600 C followed by weighing of residual inorganic sulfate ash; reflects inorganic residue content. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Electrode-based measurement of pH in a 1% w/v aqueous suspension per USP <791>. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine D10, D50, D90 values. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis via capillary tube method per USP <741>, recording onset and range of solid-to-liquid transition. |
| Microbial Limits | Membrane Filtration & Plate Count | Enumeration of aerobic mesophilic bacteria and fungi using membrane filtration followed by incubation on TSA and SDA media. |
