Manufacturing Quality Control of 4-OXO-4-(2-THIENYL)BUTYRIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities by HPLC with diode-array detection, using gradient elution and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) via headspace GC with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generation in pyridine-free reagent, based on stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other heavy metals after acid digestion, using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled acidic conditions and determines mass after ignition and drying. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against specified criteria (white to off-white crystalline powder, free-flowing). |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C and weighing residual mass after cooling in desiccator. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity (if applicable) using sodium D-line light; compound is typically achiral, so value should be near zero within instrument tolerance. |
