Manufacturing Quality Control of 2-THIOPHENECARBOXAMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~230–254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities (e.g., 2-thiophenecarboxylic acid, 2-bromothiophene) using gradient elution and UV or mass-selective detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals | ICP-MS or AAS (after acid digestion) | Quantification of elemental impurities (e.g., Pb, Cd, As, Hg) following microwave-assisted nitric acid digestion and detection by inductively coupled plasma mass spectrometry or atomic absorption spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by ignition at 700–800 °C followed by precise weighing of residual non-volatile material. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus per USP <741>, reflecting crystallinity and purity. |
| Appearance & Color | Visual Inspection / APHA Color Scale | Subjective assessment of physical state (crystalline solid) and color intensity compared to platinum-cobalt standards. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration | Separation and quantification of chloride ions via suppressed conductivity detection (IC) or argentometric titration with silver nitrate endpoint detection. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of pH in a defined saturated aqueous suspension (e.g., 1% w/v) using calibrated pH electrode, indicating acidic/basic impurity profile. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size distribution using Mie scattering theory after dispersion in air or inert gas. |
| Microbial Limits | Membrane Filtration / Plate Count | Enumeration of aerobic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
