Manufacturing Quality Control of 1-Bromonaphthalene
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of mechanical impurities. Pure product is typically colorless to light yellow crystals or crystalline powder. |
| Purity | Gas Chromatography (GC) | Separation using a capillary column with flame ionization detection (FID). The main component content is calculated by peak area normalization. Suitable for volatile organic compounds. |
| High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with UV detection (wavelength ~254 nm) and gradient elution (e.g., methanol-water) to quantitatively analyze 1-bromonaphthalene and its impurities. Suitable for thermally unstable or non-volatile substances. | |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Uses ¹H-NMR and ¹³C-NMR to confirm molecular structure by analyzing characteristic chemical shifts to determine substitution position and structural consistency. |
| Fourier Transform Infrared Spectroscopy (FT-IR) | Measures the infrared absorption spectrum of the sample and compares it with standard spectra to confirm the presence of functional groups (e.g., C-Br, aromatic ring). | |
| Bromine Content | Elemental Analysis (EA) | Determines the percentage of carbon, hydrogen, and bromine in the sample via combustion method, verifying consistency between measured composition and theoretical values. |
| Ion Chromatography (IC) or Oxygen Flask Combustion Method | Organic bromine is converted to bromide ions through oxygen flask combustion, followed by determination of total bromine content using ion chromatography or titration. | |
| Moisture Content | Karl Fischer Titration | Uses a Karl Fischer titrator to accurately measure trace moisture in the sample, applicable for both solid and liquid samples. |
| Melting Point | Melting Point Determination | Determines the melting temperature range using a melting point apparatus; compared with standard values (approximately 35–37°C) to assess purity and crystal form consistency. |
| Residual Solvents | Gas Chromatography (GC) | Detects organic solvents possibly remaining from manufacturing processes (e.g., benzene, toluene, ethanol) according to pharmacopoeia or relevant standards. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, determines the levels of heavy metal elements such as lead, mercury, cadmium, and arsenic to ensure compliance with safety limits. |
