Manufacturing Quality Control of Weinreb Linker
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; peak area comparison against main component. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, toluene) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric titration using iodine-based reagent where water reacts stoichiometrically; endpoint detected electrometrically. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for ultra-trace detection. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions on an anion-exchange column with suppressed conductivity detection. |
| pH (1% w/v aqueous solution) | pH Meter | Measurement of hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary method per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Weighing of inorganic residue remaining after high-temperature ashing (700-800 C) of sample in platinum crucible. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and enantiomeric excess. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to determine volume-based particle size distribution in dry or wet dispersion. |
