Industrial Applications of 1,8-Dihydroxyanthraquinone
| Industry | Application | Process |
|---|---|---|
| Dye Industry | Used as an intermediate for anthraquinone dyes, e.g., in the synthesis of alizarin and alizarin red analogues of natural pigments | Further functionalized via sulfonation, halogenation, or nitration to prepare dye molecules with specific structures |
| Analytical Chemistry | Employed as a colorimetric reagent or complexometric indicator for metal ions (e.g., Al, Be, Zr) | Forms colored complexes with metal ions for quantitative detection in colorimetric or spectrophotometric analysis |
| Pharmaceutical Research | Used to synthesize biologically active anthraquinone derivatives for evaluation of antitumor or antimicrobial activity | Serves as a starting material in multistep organic synthesis to construct target drug molecule scaffolds |
| Materials Science | Applied in the preparation of organic optoelectronic materials or fluorescent probes | Chemically modified by introducing electron-donating or electron-withdrawing groups to tailor optical and electrical properties |
Manufacturing Quality Control of 1,8-Dihydroxyanthraquinone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and UV spectra support structural assignment. |
| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying sample at 105 C for 2 hours under atmospheric pressure, indicating volatile content including residual solvents and moisture. |
| Residue on Ignition | Sulfated Ash (Gravimetric) | Sample ignited at 700-800 C after sulfuric acid treatment; residual inorganic ash is weighed to assess inorganic impurities. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfate Content | Gravimetric (Barium Sulfate) | Precipitation as BaSO4 after acidification and addition of barium chloride; dried precipitate is weighed to calculate sulfate. |
| Iron Content | AAS (Flame) | Atomic absorption spectroscopy at 248.3 nm following acid digestion; iron concentration determined from absorbance vs. calibration curve. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a 1% (w/v) aqueous suspension using calibrated pH electrode; reflects acidic/basic impurities or degradation products. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to determine volume-based particle size distribution in dispersed sample. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating purity and identity via comparison to reference value (249-252 C). |
| Organic Volatile Impurities (Residual Solvents) | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) using internal standard calibration. |
