Industrial Applications of H-SAR-OTBU HCL
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key chiral building block for synthesizing antiviral drugs (e.g., HCV NS5A inhibitors) | Serves as a nitrogen source in coupling reactions; target molecular scaffold is constructed via Boc deprotection followed by amidation |
| Organic Synthesis | Amino acid derivative used for N-terminal modification in solid-phase peptide synthesis | Undergoes condensation with resin-bound peptide chains on solid-phase synthesizers, delivering the tert-butoxycarbonyl (Boc)-protected sarcosine structural unit |
| Pesticide R&D | Predecessor for nitrogen-containing heterocyclic structures in novel insecticidal molecules | Pyrolidinone-based pharmacophores are constructed via cyclization reactions (e.g., condensation with aldehydes followed by oxidation) |
Manufacturing Quality Control of H-SAR-OTBU HCL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; reported as area percent relative to total chromatogram. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine/methanol medium; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for high sensitivity and specificity. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver/silver chloride electrode; endpoint detected by potential change due to AgCl precipitation. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (500-600 C) to determine inorganic ash content. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light; indicates enantiomeric purity and identity of chiral center. |
| pH (1% w/v aqueous solution) | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dispersed sample. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature range using controlled heating and visual observation of meniscus collapse. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic microorganisms and absence testing for specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
