Manufacturing Quality Control of H-D-MEPHE-OH HCL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210-220 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess assessment using a chiral stationary phase to resolve D- and L-enantiomers, with UV detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after aqueous elution. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate anion using suppressed conductivity detection with carbonate/bicarbonate eluent. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., N-methyl-L-phenylalanine, desmethyl analogs) using gradient HPLC-UV. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum, reflecting volatile and moisture content. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral identity and enantiomeric consistency. |
| pH (1% w/v aqueous solution) | Potentiometric Titration | Determination of acidity/basicity using calibrated pH electrode in aqueous suspension. |
