Manufacturing Quality Control of 2-Mercaptonicotinic 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 to 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 | Detection and quantification of volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Sulfur Content | Combustion IC | Oxidative combustion followed by ion chromatographic detection of sulfate ions to verify elemental sulfur consistency. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or discoloration against established reference standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to quantify inorganic non-volatile impurities. |
| Chloride Impurity | Ion Chromatography | Quantification of chloride anions using suppressed conductivity detection after separation on an anion-exchange column. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral purity and absence of racemization. |
