Manufacturing Quality Control of 3-CHLORO-D-ALANINE 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, calibrated against certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Separates R- and S-enantiomers on a chiral stationary phase; peak area ratio determines enantiomeric excess. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, dichloromethane) using flame ionization detection after headspace sampling. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, etc.) after acid digestion by detecting elemental ions based on mass-to-charge ratio. |
| Chloride Content | Potentiometric Titration | Determines chloride ion concentration using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Residual Acid (HCl) | Acid-Base Titration | Titrates free HCl with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., dechlorinated, hydrolyzed, or dimeric species) using gradient elution. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm using sodium D-line to confirm chiral integrity and concentration-corrected identity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated digital apparatus per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder size distribution by measuring angular scattering pattern of laser beam through dispersed sample. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects absence of specified pathogens (e.g., E. coli, Salmonella) per Ph. Eur. 2.6.12. |
