Manufacturing Quality Control of 3-BROMO-5-IODOBENZOIC ACID
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with the standard spectrum, the characteristic functional groups of 3-bromo-5-iodobenzoic acid (such as carboxyl group, aromatic ring, C–Br, and C–I bonds) can be confirmed based on the consistency of absorption peaks. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Using ¹H NMR to determine the chemical shifts, integration areas, and coupling constants of hydrogen atoms in the sample dissolved in deuterated solvent, and compare with theoretical spectra to verify the molecular structure. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column, with methanol/water or acetonitrile/water as the mobile phase, and detect with a UV detector (typically at around 254 nm). Quantify the main component using external standard method or internal standard method. |
| Acid-Base Titration | Utilize the carboxylic acid group of 3-bromo-5-iodobenzoic acid for non-aqueous or aqueous titration with a standardized sodium hydroxide solution. Determine the endpoint by phenolphthalein or potentiometry to calculate purity. | |
| Related Substances (Impurity) Check | High-Performance Liquid Chromatography (HPLC) | Separate and detect possible organic impurities (such as unreacted raw materials, by-products, degradation products) using gradient elution or isocratic elution conditions. Control the limits of each impurity using area normalization or correction factor methods. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and measure the mass loss to evaluate the content of moisture and volatile substances. |
| Ignited Residue | High-Temperature Ignition Method | Ignite the sample at high temperature (usually 700–800°C), then weigh the residual inorganic material to control the total amount of inorganic impurities. |
| Bromine and Iodine Content | Elemental Analysis (EA) or Ion Chromatography (IC) | Elemental analyzer determines total halogen content; or after oxygen bottle combustion, ion chromatography is used to determine bromide and iodide ion concentrations, verifying that the halogen ratio meets the molecular formula requirements. |
| Melting Point | Capillary Melting Point Determination Method | Determine the melting range from initial melting to final melting using a melting point apparatus, and compare with literature values (approximately 220–225°C, depending on the literature) to assess purity and crystalline consistency. |
