Manufacturing Quality Control of Z-VAL-NH2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210–220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV/MS | Separation and identification of impurities (e.g., CBZ-L-valine, diastereomers, hydrolysis/degradation products) using gradient HPLC coupled with UV and mass spectrometric detection. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess determination via chiral stationary phase chromatography, resolving L- and D-valinamide diastereomers or enantiomers. |
| Residual Solvents | GC-FID | Quantitative analysis of residual solvents (e.g., methanol, ethyl acetate, toluene) using gas chromatography with flame ionization detection against internal standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content by high-temperature incineration (500–600 °C) followed by precise weighing of residual residue. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity and identity via measurement of rotation angle of plane-polarized light in solution at specified concentration, temperature, and wavelength (e.g., Na D-line). |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Direct pH measurement using calibrated glass electrode in a standardized aqueous suspension/solution. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie theory-based light scattering to determine D10, D50, D90 values. |
| Microbial Limits | Membrane Filtration & Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods (USP <61>, <62>). |
