Manufacturing Quality Control of Boc-L-Tyrosine methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specific wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities via gradient elution and peak area comparison against reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) using flame ionization detection after headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) by plasma excitation and elemental emission intensity detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| pH of Solution | Potentiometric pH Measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode and reference electrode. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by observing temperature range over which solid transitions to liquid. |
| Appearance | Visual Inspection | Evaluates physical state, color, and clarity against defined specifications under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
