Industrial Applications of BZ-VAL-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral synthetic intermediate for the synthesis of antibiotics and antiviral agents | Prepared via acylation of L-valine with benzoyl chloride under basic conditions |
| Chemical Synthesis | Chiral auxiliary or ligand for asymmetric catalytic reactions | Coordinates with metal catalysts in organic solvents to induce stereoselective reactions |
| Research | Amino acid derivative model compound for biochemical studies | Incorporated into peptide chains via solid-phase or solution-phase peptide synthesis for structure–activity relationship studies |
Manufacturing Quality Control of BZ-VAL-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 210-230 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient reversed-phase HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20 degrees C and sodium D-line (589 nm) to confirm chiral integrity. |
| Heavy Metals | ICP-MS | Quantitative determination of Pb, Cd, Hg, As, and other regulated metals using inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 600-700 degrees C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating purity and identity via comparison to reference material. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to obtain volume-based particle size distribution (D10, D50, D90). |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, Salmonella) per USP <61> and <62>. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidity/basicity from residual reagents or degradation. |
