Manufacturing Quality Control of Benzenepropanoic acid,a-hydroxy-b-methoxy-b-phenyl-,(aS)-
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm, comparing peak area to a certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Resolves (S)- and (R)-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent; based on stoichiometric reaction of iodine with water. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., methanol, THF, toluene) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, etc.) by plasma ionization followed by mass spectrometric detection at element-specific m/z ratios. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion in sulfuric acid medium, followed by high-temperature incineration and weighing. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light; correlates with enantiomeric composition and concentration. |
| Related Substances | HPLC-UV (Forced Degradation) | Detects and quantifies structurally related impurities using stability-indicating HPLC method validated per ICH Q2(R2). |
| pH (1% w/v aqueous suspension) | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in intensity of laser light scattered by dispersed particles in liquid medium. |
| Microbial Limits | Membrane Filtration + Culture | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) using selective agar media and incubation. |
