Industrial Applications of Ethyl L-methionate hydrochloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in peptide drug synthesis (e.g., angiotensin, tyrostatin) | Serves as a C-terminal protected or modified amino acid building block in solid-phase or solution-phase peptide synthesis |
| Pharmaceuticals | Chiral building block for drug synthesis | Participates in constructing optically active drug molecules via its chiral center |
| Chemicals | Starting material for amino acid derivative synthesis | Undergoes acylation, esterification, and related reactions to produce more complex amino acid derivatives |
| Biochemical Research | Peptide synthesis and structural biology studies | Used for laboratory-scale peptide chain assembly and protein chemical modification |
Manufacturing Quality Control of Ethyl L-methionate hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Methionine Ethyl Ester Hydrochloride) | Acid-Base Titration | Quantifies active compound by neutralizing with standardized NaOH solution using bromocresol green indicator. |
| Water Content | Karl Fischer Titration | Measures water via iodometric reaction where iodine is consumed stoichiometrically by water in methanol-based medium. |
| Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring the angle of rotation of plane-polarized light at specified wavelength and temperature. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metal impurities (e.g., Pb, Cd, As) by atomization and absorption of element-specific UV-Vis radiation. |
| Chloride Content | Argentometric Titration | Measures chloride ions by titration with standardized silver nitrate solution using potassium chromate indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C and weighing residual non-volatile matter. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities using reversed-phase C18 column and UV detection. |
| pH of Solution | Potentiometric Measurement | Measures hydrogen ion activity in aqueous solution using calibrated glass electrode and reference electrode. |
| Sulfated Ash | Gravimetric Analysis | Evaluates inorganic residue after ignition with sulfuric acid pretreatment to convert metals to sulfates. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content by weight loss upon heating at 105 C under controlled atmospheric conditions. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects and enumerates aerobic microorganisms using filtration, membrane transfer, and colony formation on nutrient agar. |
| Specific Optical Rotation | Polarimetry | Confirms identity and chiral integrity by measuring optical rotation per unit concentration and path length at 20 C and 589 nm. |
