Manufacturing Quality Control of FMOC-L-2,4-DICHLOROPHE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 260-280 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample dissolved in methanol/pyridine-based reagent. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for quantitative analysis of common solvents (e.g., DMF, DCM, toluene) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element detection after acid digestion; quantifies metals (e.g., Pb, Cd, Hg, Ni) at trace levels using mass spectrometric detection. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a digital polarimeter at 20 C and sodium D-line (589 nm), confirming chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering to determine D10, D50, D90 values in compliance with ISO 13320. |
| Loss on Drying | Gravimetric Heating | Weight loss measured after drying under controlled temperature and vacuum conditions, indicating volatile and moisture content. |
| Residue on Ignition | Gravimetric Ashing | Mass of non-volatile residue after high-temperature incineration (600-800 C), indicating inorganic impurities. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
