Manufacturing Quality Control of 3-(2-THIENYL)ACRYLIC ACID 98
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A. |
| Residual Solvents | GC-FID | Headspace GC 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 trace water content via electrochemical or stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride calibration curve. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation of sulfate as barium sulfate followed by filtration, drying, and weighing to determine mass fraction. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid transforms to liquid under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against defined specifications (e.g., white to off-white crystalline powder). |
| Loss on Drying | Thermogravimetric Analysis | Mass loss measured after heating at 105 C for 2 hours; reflects volatile content including residual solvents and moisture. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator; calculated as mg KOH per g sample. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution; used to confirm chiral integrity and absence of racemization. |
