Industrial Applications of 1,5-DIHYDROXYANTHRAQUINONE
| Industry | Application | Process |
|---|---|---|
| Dye Industry | Used in the synthesis of dyes, such as disperse dyes and acid dyes | Reacted with various amines or phenols to produce dye molecules with specific hues |
| Pharmaceutical Industry | Serves as an intermediate in the synthesis of antibiotics, anticancer agents, and other pharmaceuticals | Subjected to a series of chemical modifications—including esterification, acylation, and others—to construct the target drug molecule structure |
| Pesticide Manufacturing | Used as an intermediate, particularly in the synthesis of certain fungicides and herbicides | Linked with appropriate organic groups to form biologically active pesticide compounds |
| Fine Chemicals | Used to produce functional chemicals, such as light stabilizers and antioxidants | Chemically modified—e.g., by introducing specific functional groups—to enhance product performance according to required functional properties |
| Scientific Research | Used as a laboratory reagent with broad applications in organic synthesis and materials science | Applied directly or after simple derivatization in research areas including novel material development and catalyst preparation |
Manufacturing Quality Control of 1,5-DIHYDROXYANTHRAQUINONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities (e.g., anthraquinone, 1-hydroxyanthraquinone) using gradient HPLC with UV detection. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measuring absorbance of ground-state atoms vaporized in flame or graphite furnace. |
| Sulfated Ash | Gravimetric Analysis | Weight of residue remaining after ignition with sulfuric acid treatment, indicating inorganic sulfate impurities. |
| Chloride | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Iron (Fe) | ICP-OES | Detection of atomic emission lines from ionized Fe atoms in argon plasma at characteristic wavelengths. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern generated by dispersed particles to calculate size distribution based on Mie theory. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, observed visually or via automated optical detection. |
| Organic Volatile Impurities | GC-FID | Separation by gas chromatography and quantification using flame ionization detection for residual solvents (e.g., methanol, acetone). |
| Bulk Density | USP <616> Tap Density Method | Measurement of mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
