Manufacturing Quality Control of Cbz-D-Valine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~210 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess assessment using a chiral stationary phase to resolve D- and L-enantiomers; D-isomer peak area ratio calculated relative to total valine-related peaks. |
| Residual Solvents | GC-FID | Identification and quantification of residual solvents (e.g., methanol, ethyl acetate, toluene) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, based on elemental mass-to-charge ratio detection with high sensitivity and selectivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after controlled high-temperature incineration (500–600 °C), expressed as weight percent of original sample. |
| Specific Optical Rotation | Polarimetry | Determination of chiral compound concentration and enantiomeric identity via measurement of plane-polarized light rotation in solution at specified wavelength (e.g., 589 nm) and temperature. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., N-Cbz-glycine, D-valine, benzyl alcohol) using gradient HPLC with UV detection. |
| pH (1% w/v aqueous suspension) | pH Meter | Measurement of hydrogen ion activity in a standardized aqueous suspension using a calibrated glass electrode system. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering pattern analysis to determine volume-based particle size distribution (D10, D50, D90). |
