Manufacturing Quality Control of S-TRITYL-3-MERCAPTOPROPIONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against 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 | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., methanol, acetone, toluene) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other toxic metals after acid digestion, with detection limits <0.1 ppm. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfur Content | Elemental Analyzer (Combustion-IR) | High-temperature combustion followed by infrared detection of SO2 to determine total organic sulfur content. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid sample against standard white background under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (600-800 C) to assess inorganic impurities. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to determine free carboxylic acid content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light to confirm chiral integrity and absence of racemization. |
