Industrial Applications of 4-Butylaniline
| Industry | Application | Process |
|---|---|---|
| Dye Manufacturing | Production of dye intermediates | Reacted with nitric acid to form 4-n-butylaniline nitro compound, followed by reduction to yield corresponding dye intermediates |
| Pesticide Manufacturing | Production of pesticide intermediates | Used as a raw material for synthesizing certain insecticides or herbicides |
| Pharmaceutical Manufacturing | Production of pharmaceutical intermediates | Employed to construct key structural motifs in active pharmaceutical ingredients |
| High-Performance Polymers | Synthesis of polymeric materials | Utilized as a monomer or modifier in polymerization reactions to enhance material properties |
Manufacturing Quality Control of 4-Butylaniline
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Utilizes a C18 reversed-phase column with methanol/water or acetonitrile/water as the mobile phase, and UV detection at 254 nm. Quantification is performed using external standard or internal standard methods, suitable for high-precision quantitative analysis. |
| Impurity Profile (Organic Impurities) | High-Performance Liquid Chromatography (HPLC) | Employs gradient elution to separate and detect potential impurities such as starting material residues, oxidation products (e.g., nitro derivatives), and dimers. Total impurity and individual impurity levels are calculated, complying with ICH Q3B guidelines. |
| Moisture Content | Karl Fischer Titration | Based on the specific reaction between iodine, sulfur dioxide, pyridine, and methanol with water. Moisture is quantified via electrochemical or volumetric Karl Fischer titration, achieving ppm-level accuracy, ideal for controlling moisture in organic amine compounds. |
| Melting Point | Melting Point Instrument Method | Sample is heated using a digital melting point apparatus, and the temperature range from initial melting to complete fusion is recorded. This method aids in substance identification and purity assessment; the standard melting point of 4-butylaniline is approximately 38–40°C. |
| Appearance and Color | Visual Inspection + Colorimetry (APHA) | Visual examination to confirm the sample appears as a white to pale yellow crystalline powder; if necessary, a colorimeter is used to measure APHA color values to ensure batch-to-batch consistency in product color. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, AAS or ICP-MS is used to determine levels of lead, cadmium, mercury, arsenic, and other heavy metals, ensuring compliance with pharmacopeial or REACH regulatory limits (e.g., ≤10 ppm). |
| Chloride/Sulfate Impurities | Ion Chromatography (IC) or Colorimetric Methods | IC is used to separate and detect residual chloride or sulfate ions; alternatively, nitric acid silver colorimetry (for chloride) or barium chloride precipitation method (for sulfate) may be applied for limit testing. |
| Volatile Organic Residuals | Gas Chromatography-Mass Spectrometry (GC-MS) | Headspace injection or solvent extraction is performed prior to GC-MS analysis to qualitatively and quantitatively detect residual solvents (e.g., methanol, ethanol, acetone), meeting ICH Q3C standards. |
| Nitrogen Content (Elemental Analysis) | Elemental Analyzer (CHNS/O) | Determines carbon, hydrogen, and nitrogen content via combustion oxidation. The theoretical nitrogen content for molecular formula C₁₀H₁₅N is approximately 13.7%, used for structural confirmation and supporting purity evaluation. |
| pH Value (Aqueous Solution) | pH Meter Measurement | The sample is dissolved in purified water, and pH is measured using a calibrated pH meter. As a weakly basic amine, 4-butylaniline typically exhibits a pH value between 7.5 and 9.0, useful for process monitoring. |
