Manufacturing Quality Control of 3-CHLORO-L-ALANINE HYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area against a certified reference standard. |
| Optical Rotation | [alpha]D | Measurement of specific rotation using a polarimeter at 20 degrees C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Chloride Content | Potentiometric Titration with AgNO3 | Direct titration with standardized silver nitrate solution using a silver indicator electrode to determine total chloride ion concentration. |
| Residual Solvents | GC-FID | Separation and quantification of common organic solvents (e.g., methanol, acetone, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination of water based on the stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., L-alanine, glycine, chloroacetic acid) using gradient HPLC-UV against qualified reference standards. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a 1% w/v aqueous solution using a calibrated pH meter with glass electrode. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 degrees C followed by weighing of residual inorganic sulfate ash after treatment with sulfuric acid. |
| Loss on Drying | Thermogravimetric Analysis | Measurement of weight loss upon heating at 105 degrees C for 2 hours under vacuum or dry air to determine volatile content including residual moisture and solvents. |
| Residual Catalyst (Pd) | ICP-OES | Quantification of palladium residue after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic microorganisms and absence testing for specified pathogens (e.g., E. coli, Salmonella) per pharmacopeial guidelines. |
