Manufacturing Quality Control of NALPHA-tert-Butoxycarbonyl-L-norvaline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (BOC-L-norvaline dicyclohexylamine salt) | HPLC with UV detection | Quantifies main component using reverse-phase HPLC and UV absorbance at characteristic wavelength. |
| Related Substances | HPLC with UV detection | Separates and quantifies structurally related impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., THF, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent. |
| Heavy Metals | ICP-OES | Measures total heavy metal content (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Residual Catalyst (Pd) | ICP-MS | Quantifies palladium residue at sub-pptr levels using inductively coupled plasma mass spectrometry. |
| Optical Rotation | [alpha]D measurement | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Suspension | Potentiometric pH measurement | Determines pH of a standardized suspension in water to assess acid-base balance and salt stability. |
| Loss on Drying (LOD) | Gravimetric thermogravimetry | Determines volatile content by weight loss after controlled heating under defined temperature and time. |
| Particle Size Distribution | Laser diffraction | Measures particle size distribution in dry or dispersed state using Mie scattering theory. |
| Appearance | Visual inspection | Assesses physical form, color, and homogeneity against established reference standard under controlled lighting. |
| Residue on Ignition | Gravimetric ash test | Quantifies inorganic residue remaining after high-temperature ignition of sample. |
