Manufacturing Quality Control of DEPBT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Related Substances | HPLC-UV/DAD | Separation and detection of structurally related impurities (e.g., hydrolysis products, synthesis intermediates) using gradient HPLC with diode-array detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual ethyl acetate, ethanol, toluene, and other process solvents per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying trace water based on iodine consumption in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (e.g., Pb, Cd, Hg, As) after acid digestion, achieving sub-pptr detection limits per ICH Q3D. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of inorganic ash content after controlled high-temperature incineration at 700–800 °C. |
| Optical Rotation | [α]D Measurement | Determination of specific rotation using sodium D-line light in a temperature-controlled polarimeter to confirm chiral integrity and batch consistency. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis via capillary method to verify identity and crystallinity, aligned with pharmacopeial monographs. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using Mie scattering theory to determine D10, D50, D90 values for processing suitability. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | pH determination of a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess surface acidity and stability indicators. |
