Industrial Applications of 5-Hydroxyanthranilic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Key intermediate in the synthesis of the antidepressant paroxetine | Serves as a starting material or key building block for constructing the benzodioxan ring system via diazotization, coupling, and reduction reactions |
| Pharmaceutical Industry | Intermediate in the synthesis of anticancer and anti-inflammatory drugs | Undergoes amidation, esterification, or cyclization reactions via its amino and carboxyl functional groups to construct drug molecular scaffolds |
| Dye Industry | Production of azo dyes and functional pigments | Converted to diazonium salts via diazotization, followed by coupling with appropriate components to synthesize dyes with specific hues |
| Organic Synthesis | Synthesis of 2-substituted-3-amino-4(1H)-quinolone derivatives | Acts as a cyclization precursor in condensation and ring-closure reactions with reagents such as malonic acid derivatives |
| Research Reagents | Synthesis of fluorescent probes and metal ion indicators | Modified with specific fluorophores via coordination of its hydroxyl and amino groups for selective metal ion detection |
Manufacturing Quality Control of 5-Hydroxyanthranilic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with the standard spectrum, the characteristic functional groups (such as —OH, —NH₂, —COOH) and molecular structure of 2-aminophenol-5-hydroxybenzoic acid can be confirmed. |
| Ultraviolet-Visible Spectrophotometry (UV-Vis) | Use the characteristic absorption peak at specific wavelengths (e.g., about 240–300 nm) for qualitative identification. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 column, an appropriate ratio of water-organic solvent (e.g., methanol or acetonitrile) as the mobile phase, and a UV detector (typically at 254 nm or 280 nm) to quantitatively analyze the main component content. It has high sensitivity and good repeatability. |
| Acid-Base Titration | Utilizing the acidity of the carboxyl group, titrate with a standard sodium hydroxide solution, and determine the endpoint using phenolphthalein or potentiometric method. Suitable for rough content determination. | |
| Related Substances (Impurity) Testing | High-Performance Liquid Chromatography (HPLC) | Separate and detect possible synthetic by-products or degradation products using gradient elution or isocratic elution procedures. The impurity content is usually calculated by area normalization or by the main component self-control method with correction factor. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and measure the mass percentage loss due to moisture or volatile components. |
| Residue on Ignition | High-Temperature Ignition Method | Ignite the sample at high temperature (usually 700–800°C) and weigh the residual inorganic material to assess the content of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Colorimetry) or Atomic Absorption Spectrometry (AAS) | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic by reacting with thioacetamide to form colored precipitates for visual colorimetric analysis, or by using AAS for precise measurement. |
| pH Value | pH Meter Measurement | Prepare a solution of a certain concentration (e.g., 1% w/v) and measure its pH value using a calibrated pH meter, reflecting the free acid/alkali state. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a melting point apparatus. It serves as an auxiliary indicator for purity and identity confirmation (literature melting point is approximately 200–205°C, decomposition). |
