Industrial Applications of 2-Amino-3-[(4-methoxybenzyl)thio]propanoic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a synthetic drug intermediate for developing bioactive compounds | S-(4-Methoxybenzyl) protection is introduced onto the thiol group of L-cysteine via organic synthesis to form a stable intermediate, subsequently employed in constructing sulfur-containing amino acid-based drug molecules |
| Biotechnology | Used as a protected amino acid derivative in peptide synthesis | Applied as a cysteine analog for side-chain protection in solid-phase or solution-phase peptide synthesis, preventing nonspecific oxidation or cross-linking of the thiol group during reactions |
| Chemical Research | Used as a model compound for studying thiol chemistry and enzyme catalytic mechanisms | Emulates the reactivity of native cysteine to investigate its roles in redox reactions, metal ion chelation, and enzyme active sites |
Manufacturing Quality Control of 2-Amino-3-[(4-methoxybenzyl)thio]propanoic acid
| 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 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 residual solvents (e.g., methanol, acetone, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element determination of Pb, Cd, As, Hg, and Ni after acid digestion, based on atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at 20 deg C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a 1% w/v aqueous solution using calibrated glass electrode and pH meter. |
| Residue on Ignition | Gravimetric Analysis | Weighing of inorganic residue remaining after incineration at 600-700 deg C, indicating non-volatile inorganic impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size distribution using Mie scattering theory applied to laser diffraction patterns. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) following USP <61> and <62>. |
| Appearance | Visual Inspection | Assessment of physical form, color, and clarity of solid material against established reference standards under controlled lighting conditions. |
