Manufacturing Quality Control of 4-Pyridinamine,2,5-dichloro-(9CI)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances (Impurities) | HPLC-UV or UPLC-UV | Separation and quantification of structurally related impurities (e.g., mono-chloro analogs, nitro precursors, hydrolysis products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID or GC-MS | Headspace gas chromatography with flame ionization detection or mass spectrometry to quantify residual solvents (e.g., DMF, methanol, dichloromethane) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, achieving sub-ppb sensitivity and compliance with ICH Q3D. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Direct titration with standardized silver nitrate solution using a silver indicator electrode; based on precipitation of AgCl. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical generation of iodine to react stoichiometrically with water in anhydrous medium; suitable for low-level moisture determination (<0.1%). |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating; used for identity confirmation and purity assessment (sharp range indicates high purity). |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Ignition at 700–800 °C followed by weighing of inorganic residue; indicates presence of inorganic salts or catalyst residues. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volumetric particle size distribution in dispersed solid samples. |
| pH of Aqueous Suspension | pH Meter (10% w/v suspension) | Measurement of hydrogen ion activity in a standardized aqueous suspension to assess acidic/basic impurities or degradation. |
| Optical Rotation | [α]D Measurement (Polarimetry) | Determination of specific rotation at sodium D-line to confirm chiral integrity (though compound is achiral, used to detect chiral contaminants or enantiomeric impurities if present). |
