Manufacturing Quality Control of 1,3-Bis(aminomethyl)benzene
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with water-methanol or water-acetonitrile as the mobile phase, and UV detection at 254 nm. Quantification is performed using external or internal standard methods, effectively separating impurities. |
| Moisture Content | Karl Fischer Titration | Utilizes Karl Fischer reagent (containing iodine, sulfur dioxide, pyridine, and methanol) that reacts specifically with water. The endpoint is determined by potentiometric or coulometric titration, enabling accurate measurement of trace moisture content. |
| Color (Appearance) | Platinum-Cobalt Colorimetry (APHA/Hazen) | Compares sample color visually or via spectrophotometry with standard platinum-cobalt color scale solutions, expressed in Pt-Co units to assess product color intensity and reflect refining degree and oxidation impurity levels. |
| Acid Value (Free Acid) | Acid-Base Titration | Titrates free acids (e.g., benzoic acid and other oxidation products) in the sample using standardized sodium hydroxide solution, with phenolphthalein as indicator. Acid value (mg KOH/g) is calculated to evaluate degradation level. |
| Impurity Profile (Organic Impurities) | Gas Chromatography-Mass Spectrometry (GC-MS) | After derivatization or direct injection, samples are separated by GC and detected by MS for qualitative and quantitative analysis of residual solvents, monoamine by-products (e.g., m-toluidine), dimers, and other organic impurities. |
| Melting Point | Melting Point Determination (Capillary or Automatic Melting Point Apparatus) | Measures the melting temperature range using capillary tube method or automatic melting point instrument. Compared with reference values (~48–50°C) to assess purity and crystal form consistency. |
| Boiling Point / Distillation Range | Petroleum Product Distillation Method (ASTM D86) | Distills the sample under atmospheric or reduced pressure, recording initial boiling point, dry point, and distillation range. Used to evaluate volatile impurities and batch-to-batch stability. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, heavy metals such as lead, cadmium, mercury, and arsenic are quantified using AAS or Inductively Coupled Plasma Mass Spectrometry (ICP-MS), ensuring compliance with food/pharmaceutical standards (e.g., ICH Q3D). |
| Chloride Content | Ion Chromatography (IC) | Sample aqueous solution is separated via ion exchange column, and chloride ions are detected by conductivity detector. Concentration is determined by comparison with a calibration curve, assessing residue from raw materials or process contaminants. |
| pH Value (Aqueous Solution) | pH Meter Method | Sample is prepared as an aqueous solution (e.g., 1%) and pH measured using a calibrated pH meter to assess alkalinity and detect possible interference from acidic impurities. |
