Manufacturing Quality Control of Pyrrole-2-carboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| 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 mass spectrometry for ultra-trace sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection with a carbonate eluent. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; onset and range indicate crystallinity and purity. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode system. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate volume-based particle size distribution. |
| Microbial Contamination | Membrane Filtration and Plate Count | Quantitative recovery of viable aerobic microorganisms from dissolved sample via filtration, followed by incubation on nutrient agar. |
