Manufacturing Quality Control of 5-Methyl-2-thiophenecarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 230-254 nm, based on peak area comparison 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 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 water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange column separation. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using suppressed conductivity detection following anion exchange column elution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid-to-liquid phase change occurs. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the bulk sample under controlled white light against defined standards (e.g., white crystalline powder). |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile inorganic residue remaining after high-temperature incineration (700-800 C), expressed as percentage of original sample weight. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volumetric particle size distribution in dry or wet dispersion mode. |
