Manufacturing Quality Control of BOC-L-TYR(ALL)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase; L-isomer content determined by relative peak area. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, THF, MeOH) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine trace water based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) via inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residues using inductively coupled plasma optical emission spectroscopy after microwave digestion. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or foreign matter under controlled white light. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating crystallinity and purity. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., deprotected, oxidized, or dimeric species) using gradient elution. |
| Residual Chloride | Ion Chromatography | Quantification of chloride ions after aqueous extraction using suppressed conductivity detection. |
| Microbial Contamination | Bioburden Testing (Membrane Filtration) | Enumeration of viable aerobic microorganisms per USP <61> using membrane filtration followed by incubation on soybean-casein digest agar. |
