Industrial Applications of N-Ethyl-N-hydroxyethylaniline
| Industry | Application | Process |
|---|---|---|
| Dye Industry | Intermediate for azo dyes, used in the synthesis of acid, direct, and reactive dyes | Diazotization-coupling reaction; coupling with diazonium salts to produce azo dyes |
| Pharmaceutical Industry | Intermediate for local anesthetics (e.g., benzocaine derivatives) and antimalarial drugs | Reduction, acylation, or alkylation modifications to construct the active molecular scaffold |
| Rubber Industry | Intermediate for rubber antioxidants | Condensation with aldehydes or oxidation to yield amine derivatives exhibiting antioxidant activity |
| Analytical Chemistry | pH indicator and colorimetric reagent for metal ions | Protonation/deprotonation in buffered systems induces color change; forms colored complexes with metal ions such as Fe³⁺ and Cu²⁺ |
Manufacturing Quality Control of N-Ethyl-N-hydroxyethylaniline
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Uses a C18 chromatographic column with methanol-water or acetonitrile-water as the mobile phase, detected by a UV detector (typically at 254 nm). Quantification is performed via external standard or internal standard methods, suitable for high-precision quantitative analysis. |
| Impurity Profile (Organic Impurities) | HPLC-UV / HPLC-MS | Employs gradient elution HPLC to separate impurities, combined with UV detection or mass spectrometry (LC-MS) for qualitative and quantitative identification of impurities such as unreacted starting materials, oxidation products, and diethylated by-products. |
| Water Content | Karl Fischer Titration | Utilizes an iodine-sulfur dioxide-pyridine-methanol system that reacts quantitatively with water; measurement is carried out via electrochemical or volumetric methods to determine trace water content, compliant with pharmacopoeial standards (e.g., USP/EP), with precision at ppm level. |
| Boiling Point / Distillation Range | Distillation Method / Boiling Point Apparatus | Measures the boiling range using atmospheric or reduced-pressure distillation equipment to determine the presence of low-boiling-point solvent residues or high-boiling-point impurities, in accordance with industrial specification requirements (typical boiling point: ~265–270°C). |
| Color (Appearance) | Platinum-Cobalt Color Scale (APHA Color) | Compares the sample against standard platinum-cobalt solutions and expresses color intensity in Hazen units (Pt-Co) to assess discoloration due to oxidation or impurities, suitable for appearance quality control. |
| Acid Value / Base Value | Acid-Base Titration | Titrates the sample with standardized sodium hydroxide or hydrochloric acid solution to determine free acid or base content, evaluating the presence of acidic oxidation products (e.g., phenolic compounds) or basic catalyst residues. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, heavy metals such as lead, cadmium, mercury, and arsenic are measured using AAS or ICP-MS, complying with ICH Q3D or pharmaceutical-grade limits (typically ≤10 ppm). |
| Solvent Residues | Gas Chromatography (GC-FID / GC-MS) | Employs headspace or direct injection GC methods to detect residual solvents (e.g., ethanol, ether, benzene), evaluating compliance with ICH Q3C residual solvent limits. |
| Refractive Index | Refractometry | Measures the refractive index of the sample at 20°C or 25°C using a digital refractometer (typical range: ~1.595–1.605), serving as a physical constant for auxiliary identification and purity assessment. |
| Melting Point (Solid Samples) | Capillary Melting Point Apparatus | If the sample is solid (e.g., low-temperature crystallization), the melting point range is determined (N-ethyl-N-hydroxyethyl aniline is typically a liquid and not applicable; however, this method can detect crystalline impurities). |
