Manufacturing Quality Control of 5-METHYL-1H-PYRAZOLE-3-CARBOXYLIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 220 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric electrochemical reaction. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for simultaneous detection and quantification of elemental impurities (e.g., Pb, Cd, As, Hg) at sub-pptr levels. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and weighing of residual inorganic ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature range using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assessment of color and physical state (crystalline powder) against standard reference under controlled lighting and white background. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to assess chiral purity and identity. |
| pH of Aqueous Suspension | pH Meter | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering principle to generate volume-based particle size distribution profile. |
