Manufacturing Quality Control of 2-METHYL-1H-PYRROLE-3-CARBOXYLIC ACID ETHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., ethanol, ethyl acetate) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic detection for high sensitivity and selectivity. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference samples under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light in solution to assess chiral purity and identity. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after controlled high-temperature ashing to determine inorganic impurity content. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to generate volumetric particle size distribution profile. |
