Manufacturing Quality Control of Z-Asp(OtBu)-OH·H2O

Detection Item Common Analytical Method Method Overview
Assay (Purity) HPLC-UV Quantifies main component using reverse-phase HPLC with UV detection at 210 nm based on peak area comparison against reference standard.
Related Substances HPLC-UV Detects and quantifies structurally related impurities using gradient HPLC with UV detection; identified by retention time and relative response.
Residual Solvents GC-FID Measures volatile organic solvents (e.g., ethyl acetate, isopropanol) by gas chromatography with flame ionization detection using internal standard calibration.
Water Content Karl Fischer Titration Determines water content via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water.
Heavy Metals ICP-OES Quantifies trace metal impurities (e.g., Pb, Cd, Ni) after acid digestion by measuring elemental emission intensities in plasma.
Chloride Content Ion Chromatography Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection.
Sulfated Ash Gravimetric Analysis Measures inorganic residue after high-temperature incineration of sample with sulfuric acid pretreatment.
Optical Rotation Polarimetry Determines specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity.
Melting Point Capillary Melting Point Apparatus Measures temperature range at which solid transitions to liquid, indicating crystallinity and purity.
Particle Size Distribution Laser Diffraction Analyzes size distribution of solid particles in suspension by measuring angular variation of scattered laser light.
pH of Aqueous Suspension Potentiometric pH Measurement Determines pH of a defined suspension in water using calibrated glass electrode and pH meter.
Microbial Contamination Membrane Filtration Detects aerobic microorganisms by filtering sample solution, culturing on soybean-casein digest agar, and counting colony-forming units.
