Industrial Applications of L-tert-Leucine methyl ester hydrochloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral drug intermediates for synthesizing protease inhibitors, antiviral agents, and peptide-based therapeutics | Used as chiral building blocks in asymmetric synthesis or solid-phase/liquid-phase peptide synthesis |
| Biochemical Research | Construction of non-natural amino acid-modified peptides for structure–activity relationship (SAR) studies | Introduced into peptide chains via Fmoc- or Boc-based protection strategies for solid-phase peptide synthesis (SPPS) |
| Agrochemicals | Potential chiral intermediates for developing highly selective pesticide molecules | Employed in chiral catalysis or condensation reactions to construct active molecular scaffolds |
Manufacturing Quality Control of L-tert-Leucine methyl ester hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to reference standard. |
| Chiral Purity | Chiral HPLC | Separates enantiomers on a chiral stationary phase and quantifies L-isomer excess relative to D-isomer. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration using iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (Pb, Cd, Hg, As, etc.) via inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Content | Potentiometric Titration | Determines chloride ions by titration with silver nitrate using silver/silver chloride indicator electrode. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode pH meter. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric identity and purity by measuring rotation of plane-polarized light at 20 C using sodium D-line. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., diastereomers, hydrolysis products) using gradient HPLC. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam. |
| Microbial Limits | Membrane Filtration | Determines total aerobic microbial count and absence of specified pathogens (E. coli, Salmonella) per pharmacopeial methods. |
