Manufacturing Quality Control of 3-BROMO-1H-PYRROLE-2-CARBOXYLIC ACID METHYL 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 or UPLC-MS | Separation and identification/quantification of impurities (e.g., unreacted bromopyrrole, hydrolysis products, isomers) using gradient elution and spectral confirmation. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, dichloromethane, toluene) 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. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation; suitable for low-water samples (<1000 ppm) with high precision. |
| Residue on Ignition | Gravimetric Analysis | Weighing inorganic residue remaining after controlled high-temperature ashing (700–800 °C), indicating inorganic impurities or catalyst residues. |
| Optical Rotation | [α]D Measurement | Polarimetric measurement at 589 nm to confirm chiral integrity (though compound is achiral, used to detect chiral contaminants or degradation). |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis to verify identity and crystallinity; deviation indicates polymorphic forms or impurities. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Quantification of chloride ions (e.g., from residual HCl or chlorinated by-products) using suppressed conductivity detection or AgNO₃ titration. |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment against water-white standard and colorimetric comparison to detect discoloration due to degradation or metal contamination. |
