Industrial Applications of Acid Red 87
| Industry | Application | Process |
|---|---|---|
| Biomedical & Life Sciences | Biological staining, cytoplasmic staining, fluorescence microscopy | Applied in fluorescence microscopy by adsorption onto cytoplasm to visualize cellular structures |
| Biomedical & Life Sciences | Vital staining (e.g., lymphatic vessels, corneal tissue tracing) | Applied to or injected into living tissues as a dilute solution for localization and observation via fluorescence |
| Cosmetics & Personal Care | Hair dye, colorant in hair care products | Incorporated as a colorant into hair dye formulations or shampoos to impart color or dyeing performance |
| Textile Dyeing & Printing Industry | Dyeing of protein fibers (e.g., silk, wool, nylon) | Applied in acidic dye baths, where the dye anion binds to cationic groups on the fiber |
| Textile Dyeing & Printing Industry | Fluorescent whitening or vivid red tinting of fabrics | Applied in fabric finishing to enhance whiteness or color vividness using its fluorescent properties |
| Analytical Chemistry | Fluorescent reagent in fluorometric analysis | Used as a fluorescent probe for quantitative or qualitative analysis based on fluorescence intensity changes |
| Organic Synthesis Industry | Synthesis of other dyes and intermediates | Converted into structurally specific dye intermediates via chemical reactions (e.g., reduction, halogenation) |
Manufacturing Quality Control of Acid Red 87
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at λmax (≈510 nm) using a calibrated standard curve in specified solvent (e.g., 1% NaOH). |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content after acid digestion by quantifying atomic absorption of ground-state metal atoms in flame or graphite furnace. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in anhydrous methanol/pyridine medium. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 °C) | Residue mass after high-temperature incineration reflects non-volatile inorganic impurities; reported as % w/w. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode and reference electrode. |
| Chloride Content | Argentometric Titration (Mohr Method) | Quantifies chloride ions by titration with standardized AgNO3 solution using K2CrO4 indicator for endpoint detection. |
| Substance Not Precipitated by Acetic Acid | Gravimetric Filtration & Drying | Measures insoluble impurities after treating sample with dilute acetic acid, filtering, drying, and weighing residue. |
| Color Strength (Relative to Standard) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample and certified reference dye solution under identical conditions to assess batch-to-batch color intensity consistency. |
