| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 260 nm. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase with UV detection; L-isomer content determined relative to total threonine-related peaks. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, DCM, methanol) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, Ni) via plasma ionization and mass spectrometric detection. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residues by atomic emission spectroscopy following acid digestion and nebulization. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., deprotection by-products, diastereomers) using gradient reversed-phase HPLC. |
| Optical Rotation | Polarimetry | Measurement of specific rotation at 20 degrees C using sodium D-line (589 nm) light to confirm stereochemical integrity. |
| Particle Size Distribution | Laser Diffraction | Determination of particle size distribution in suspension using Mie scattering theory and optical detection of diffracted laser light. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum conditions, indicating volatile and moisture content. |
