Manufacturing Quality Control of BOC-D-GLU-OTBU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient reversed-phase HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., MTBE, DCM, MeOH) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Optical Rotation | [alpha]D | Measurement of specific optical rotation using a polarimeter at 20 degC with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Heavy Metals | ICP-MS | Quantitative determination of elemental impurities (e.g., Pb, Cd, Ni, Cu) after acid digestion, using inductively coupled plasma mass spectrometry per ICH Q3D. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after aqueous extraction. |
| Residual Tert-Butyl Alcohol | GC-FID | Direct injection or headspace GC-FID analysis to detect and quantify residual t-BuOH from incomplete deprotection or synthesis carryover. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of pH in a 1% w/v aqueous suspension using a calibrated pH meter with glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis by controlled heating of crystalline sample to observe solid-to-liquid transition range. |
| Loss on Drying | Gravimetric Method | Weight loss measured after drying under vacuum at 60 degC for 2 hours, indicating volatile and moisture content. |
| Microbial Contamination | Membrane Filtration | Quantitative detection of aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration per USP <61>. |
