Manufacturing Quality Control of NALPHA-9-Fluorenylmethoxycarbonyl-N-benzylglycine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 268 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., FMOC-glycine, benzyl glycine, di-FMOC derivatives) using gradient HPLC-UV; identification by retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., DMF, DCM, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals (as Pb) | ICP-MS | Quantification of trace heavy metals (Pb, Cd, Cr, Ni, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr detection. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration curve. |
| Optical Rotation | [α]D | Measurement of specific optical rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm chiral integrity and absence of racemization. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, indicating crystallinity and purity (sharp range expected). |
| Residue on Ignition | Gravimetric Analysis | Weighing residue after high-temperature (700–800 °C) incineration to assess inorganic ash content. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering to determine D10, D50, D90 values per ISO 13320. |
| Microbial Contamination | Membrane Filtration & Plate Count | Enumeration of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per Ph. Eur. 5.1.4. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) to detect acidic/basic degradation products or residual reagents. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Weight loss upon heating under controlled nitrogen atmosphere (105 °C, 2 h) to determine volatile content including residual solvents and moisture. |
| Identity Confirmation | FT-IR Spectroscopy | Comparison of sample infrared absorption spectrum (KBr pellet) against reference standard to verify functional group fingerprint (e.g., FMOC carbamate C=O, benzyl C–H). |
