Manufacturing Quality Control of 141109-19-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV/MS | Separation and identification of impurities (e.g., starting materials, degradants, isomers) via gradient HPLC coupled with UV and/or mass spectrometric detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., methanol, dichloromethane, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water based on iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Direct titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Optical Rotation | [α]D | Measurement of specific rotation at 589 nm (Na D-line) using a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration (~750 °C) followed by precise weighing of residual residue. |
| pH of Solution (1% w/v in water) | pH Potentiometry | Measurement of aqueous solution pH using calibrated glass electrode to assess acidity consistent with hydrochloride salt form. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering to determine D10, D50, D90 values per USP <429>. |
