Manufacturing Quality Control of Pyridazine, 3,6-dione, 4-bromo-1,2-dihydro-
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV or UPLC-UV | Separation and quantification of structurally related impurities (e.g., starting materials, intermediates, degradation products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., dichloromethane, ethyl acetate, methanol) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic elements (e.g., Pb, Cd, Hg, As) after acid digestion, offering sub-pptr detection limits compliant with ICH Q3D. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Determination of inorganic residue after controlled charring and sulfuric acid treatment followed by high-temperature incineration (500–600 °C). |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; confirms identity and detects gross impurities via depression/broadening. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of chloride ions after sample dissolution and filtration, per USP <231> and EP 2.4.18. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed powder to determine D10, D50, D90 values, relevant for downstream processing and formulation consistency. |
| Specific Optical Rotation | [α]D Measurement | Polarimetric determination at 20 °C using sodium D-line (589 nm) to confirm stereochemical integrity and detect chiral contaminants (if applicable). |
