Manufacturing Quality Control of 3,4-Diaminotoluene
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase chromatographic columns for sample separation and UV detection (e.g., 254 nm) to quantify the main component and impurities, assessing purity. Suitable for trace impurity detection. |
| Content Determination | Titration Method (Bromate or Sodium Nitrite Titration) | Based on redox reactions or diazotization of aromatic primary amine groups; the content of the main component is calculated via titration with standard solutions. Simple operation and low cost. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Confirms molecular structural consistency by comparing characteristic absorption peaks (e.g., -NH₂ stretching vibration, benzene ring skeleton vibration) with reference spectra. |
| Impurity Identification and Semi-Quantification | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates volatile impurities and identifies their structures using mass spectrometry, suitable for identifying and semi-quantifying isomeric or by-product impurities. |
| Moisture Content Determination | Karl Fischer Titration | Quantitatively determines trace moisture in samples through the reaction between iodine and sulfur dioxide in a pyridine/methanol system, providing high accuracy. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, ICP-MS detects trace levels of heavy metals such as lead, cadmium, mercury, and arsenic with high sensitivity, ensuring compliance with pharmacopoeial or industrial standards. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Utilizes headspace injection to separate and detect residual organic solvents (e.g., toluene, ethanol) using FID or MS detectors, compliant with ICH guidelines. |
