Manufacturing Quality Control of METHYL 1H-PYRAZOLE-4-CARBOXYLATE HYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~210–230 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, degradation products) using gradient HPLC-UV with system suitability criteria per ICH Q2(R2). |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, dichloromethane) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, As, Hg) after acid digestion, with detection at sub-pptr levels per ICH Q3D. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Direct titration using silver nitrate; endpoint detected by silver-selective electrode based on formation of AgCl precipitate. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Incineration at 750–800 °C followed by sulfuric acid treatment and weighing of inorganic residue per USP <281>. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; indicative of crystallinity and purity per USP <741>. |
| pH (1% w/v aqueous suspension) | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension, reflecting residual acidity from HCl salt formation. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volumetric particle size distribution (D10, D50, D90) per ISO 13320. |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation using sodium D-line (589 nm); verifies chiral integrity if applicable (though compound is achiral, used for batch consistency). |
