Manufacturing Quality Control of 2-Bromo-4,6-dinitroaniline
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Utilizes a reverse-phase C18 column with mobile phases such as methanol/water or acetonitrile/buffer salt, quantifying the main component purity using a UV detector (e.g., at 340 nm); suitable for trace impurity analysis. |
| Structure Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Confirms molecular structure consistency by comparing characteristic absorption peaks (e.g., —NH₂, —NO₂, C—Br functional groups) with reference spectra. |
| Molecular Weight and Structure Verification | Mass Spectrometry (MS) | Employs ESI or EI ionization sources to measure molecular ion peaks ([M+H]⁺ or M⁺•), and verifies structure through fragment ion patterns; often coupled with LC (LC-MS). |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Applicable for analysis of volatile or semi-volatile organic impurities; identifies unknown impurities via retention time and mass spectral library matching. |
| Melting Point Determination | Capillary Melting Point Apparatus | Measures the temperature range at which a substance transitions from solid to liquid; used as a physical constant for preliminary assessment of purity and identity. |
| Loss on Drying | Oven Drying Method | Dries the sample at a specified temperature (e.g., 105°C) to constant weight and calculates the percentage of mass loss to evaluate water or volatile substance content. |
| Residue on Ignition | High-Temperature Incineration Method | Ashes the sample at high temperature (e.g., 600–800°C) and weighs the residual inorganic material to control levels of inorganic impurities. |
| Heavy Metal Limit | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measures concentrations of heavy metal elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopeial or industrial standard limits. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Uses headspace sampling to separate and quantify organic solvent residues such as methanol, ethanol, and acetone, in accordance with ICH Q3C guidelines. |
| Appearance and Color | Visual Color Comparison | Observes the solid color (typically yellow to orange-red crystals) under natural or standard lighting by comparison with standard solutions or color charts to detect abnormalities. |
