Manufacturing Quality Control of (3S,4S)-1-Benzylpyrrolidine-3,4-diol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Chiral Purity | (S,S)-Enantiomeric Excess | Chiral HPLC with chiral stationary phase (e.g., Chiralpak AD-H), comparing retention times and peak areas of enantiomers. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities using gradient HPLC with diode-array detection, relative to main peak response. |
| Residual Solvents | GC-FID | Quantifies volatile organic solvents (e.g., MeOH, EtOAc, toluene) by headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent in pyridine-free solvent. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (Pb, Cd, Hg, As, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by ignition at 700-800 C followed by precise weighing of residual residue. |
| Optical Rotation | Polarimetry | Determines specific optical rotation using sodium D-line light (589 nm) in solution, confirming chiral integrity. |
| pH (1% w/v aqueous suspension) | pH Meter | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode pH meter. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and specified pathogens (e.g., E. coli, S. aureus) via filtration, culture, and colony enumeration. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference samples. |
