Manufacturing Quality Control of 3-Iodo-thiophene-2-carboxylic acid Methyl ester
| 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 to a certified reference standard. |
| Identity | FTIR Spectroscopy | Confirmation of molecular structure by matching characteristic absorption bands (e.g., C=O, C-I, aromatic C-H) to reference spectrum. |
| Identity | 1H NMR Spectroscopy | Structural verification via proton chemical shifts, coupling patterns, and integration ratios consistent with the target molecule. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., methanol, dichloromethane) using flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in a pyridine-methanol-sulfur dioxide reaction with water. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; quantification via atomic emission intensity at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection. |
| Residual Palladium | ICP-MS | Ultra-trace quantification of Pd catalyst residue after microwave-assisted digestion, using mass-selective detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards under controlled lighting conditions. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator. |
| Related Substances | HPLC-DAD | Detection and quantification of structurally related impurities using diode array detection and relative response factors. |
