Manufacturing Quality Control of 3-Iodophenylacetic acid
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state (e.g., white or off-white crystalline powder), and presence of visible impurities with the naked eye to determine compliance with quality specifications. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) Proton Nuclear Magnetic Resonance (¹H NMR) |
- IR: Record the infrared absorption spectrum of the sample and compare it with that of a reference standard to confirm characteristic functional groups (e.g., carboxyl, aromatic ring, C–I bond); - HPLC: Compare the retention time of the sample with that of the reference standard under specified chromatographic conditions; - ¹H NMR: Analyze chemical shifts and coupling constants of hydrogen atoms to verify molecular structural features. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase and a UV detector (typically at around 254 nm) to detect 3-iodophenylacetic acid. Calculate the content using external standard or area normalization method to ensure purity meets specifications (typically ≥98.0%). |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Under the same or optimized chromatographic conditions as used in the assay, detect and quantify potential organic impurities (e.g., unreacted starting materials, by-products, degradation products). Use the standard substance comparison method or main component self-comparison method with correction factors to control limits for individual and total impurities. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Atmospheric Drying | Dry the sample at 105°C to constant weight and measure the percentage weight loss to control moisture and volatile content (typically required ≤0.5%). |
| Sulfated Ash | High-Temperature Incineration | Treat the sample with sulfuric acid, then incinerate at 700–800°C to constant weight. Measure the residual inorganic matter (ash) to control inorganic impurities (typically required ≤0.1%). |
| Heavy Metals | Thioacetamide Method (Colorimetry) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | - Colorimetry: In acidic conditions, heavy metals react with thioacetamide to form colored precipitates, which are compared to a standard lead solution; - ICP-MS: Highly sensitive quantitative determination of elemental impurities such as lead, mercury, cadmium, and arsenic; suitable for strict control of metal residues. |
| pH (if prepared as a solution) | pH Meter Method | Dissolve the sample in water to a specified concentration (e.g., 1%), and measure the pH using a calibrated pH meter to evaluate acidity and the presence of acidic or basic impurities. |
