Industrial Applications of 5-Aminoisophthalic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing antitumor agents (e.g., gemcitabine derivatives) and antimicrobial compounds | Produced via diazotization-hydrolysis or catalytic hydrogenation reduction of 5-nitroisophthalic acid; subsequently employed in multi-step reactions—including amidation and cyclization—to construct active molecular frameworks |
| Dyes | Key monomer for manufacturing high-performance azo dyes and reactive dyes, used in dyeing polyester and cellulosic fibers | Coupled with diazonium salts to form azo structures; or subjected to chlorosulfonation followed by condensation with cyanuric chloride to introduce reactive groups, yielding reactive dye intermediates |
| High-performance polymers | Comonomer for synthesizing heat-resistant polyamides, polyesters, and liquid crystalline polymers | Undergoes melt polycondensation with diamines or diols under nitrogen atmosphere at 280–320 °C, incorporating rigid meta-aminobenzoic acid structural units to enhance thermal stability |
| Pesticides | Structural building block for synthesizing novel herbicides and plant growth regulators | After diazotization, coupled with phenolic compounds or reacted with aldehydes via Mannich reaction to construct biologically active side chains containing amino-substituted aryl rings |
Manufacturing Quality Control of 5-Aminoisophthalic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural or standard lighting to determine if it is white to off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) | Perform infrared scanning of the sample and reference standard under identical conditions; compare characteristic absorption peaks (e.g., functional groups such as —NH₂, —COOH). |
| Proton Nuclear Magnetic Resonance (¹H-NMR) | Dissolve the sample in a deuterated solvent and record the ¹H-NMR spectrum; confirm structural consistency through chemical shifts, peak shapes, and integration areas. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically around 254 nm); quantify the main component using external or internal standard methods. |
| Titration (Acid-Base Titration) | Titrate the carboxyl group's acidity using a standardized NaOH solution, with phenolphthalein or potentiometric detection for endpoint determination; calculate active ingredient content. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate impurities using gradient or isocratic elution; calculate individual impurity levels using reference standards or the area normalization method. |
| Water Content | Karl Fischer Titration | Determine water content using coulometric or volumetric Karl Fischer methods, suitable for trace moisture analysis. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) to constant weight and calculate the percentage weight loss, indicating volatile impurities or residual solvents. |
| Residue on Ignition (Sulphated Ash) | Sulphated Ash Method | Ignite the sample at high temperature, treat with sulfuric acid, then weigh the residue to assess inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure concentrations of heavy metal elements such as lead, cadmium, mercury, and arsenic; ensure compliance with pharmacopoeial or customer-specified limits. |
| Solubility | Solubility Test | Test solubility in various solvents such as water, ethanol, acetone, and DMSO; used for process development and formulation guidance. |
| Particle Size Distribution | Laser Diffraction Analysis (LDA) | Disperse the sample using wet or dry methods to measure particle size parameters such as D10, D50, and D90, ensuring consistent physical properties across batches. |
| Crystal Form | X-Ray Powder Diffraction (XRD) | Analyze characteristic diffraction peaks to identify crystal structure and detect polymorphic forms, ensuring batch-to-batch consistency in crystallinity. |
