Industrial Applications of DL-VALINE METHYL ESTER HYDROCHLORIDE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Chiral intermediate for synthesizing antihypertensive and anticancer drugs | Used as a chiral auxiliary or building block; incorporated into target molecules via hydrolysis, acylation, coupling, and related reactions |
| Pharmaceuticals | Raw material for amino acid–based drugs, e.g., compound amino acid injection solutions | Formulated with other amino acids after deprotection, salt formation, and purification |
| Pesticides | High-efficacy, low-toxicity insecticide intermediate, e.g., for synthetic pyrethroid synthesis | Involved in condensation, cyclization, and related reactions to construct the active molecular scaffold |
| Food | Food additive (nutritional fortificant) for supplementing essential amino acids | Incorporated into specialized dietary foods or nutritional supplements following refinement and standardization |
Manufacturing Quality Control of DL-VALINE METHYL ESTER HYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DL-Valine Methyl Ester Hydrochloride) | Acid-Base Titration with NaOH | Quantifies the main component by neutralizing the hydrochloride salt with standardized sodium hydroxide solution using an indicator or potentiometric endpoint. |
| Water Content | Karl Fischer Titration | Determines water content based on the stoichiometric reaction of iodine with sulfur dioxide and water in a methanol-based reagent. |
| Residual Solvents (Methanol, Ethyl Acetate) | Gas Chromatography (GC) with FID | Separates and quantifies volatile organic solvents using a capillary column and flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Measures trace heavy metal concentrations by atomizing and ionizing the sample in plasma and detecting mass-to-charge ratios. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Quantifies chloride ions by titration with silver nitrate using a silver indicator electrode to detect the endpoint. |
| Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution at specified concentration and path length. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and ultraviolet absorbance detection. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C and weighing the residual residue after cooling. |
| pH (1% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous solution using a calibrated glass electrode system. |
| Particle Size Distribution | Laser Diffraction | Determines particle size distribution by analyzing angular variation in laser light scattering from a dispersed sample. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtering sample through membrane, culturing on agar media, and counting colony-forming units. |
| Appearance and Color | Visual Inspection and Hazen Color Scale | Assesses physical state and color by comparison against standard platinum-cobalt solutions under controlled lighting conditions. |
