Applications of 517-28-2
| Industry | Application | Process |
|---|---|---|
| Medical/Pathological | Nuclear staining in tissue sectioning | Used in hematoxylin and eosin (H&E) staining, typically combined with mordants (e.g., aluminum or iron salts) to form complexes that selectively stain DNA in cell nuclei |
| Biological Research | Nuclear counterstain in microscopy sample preparation | Applied as a counterstain to fixed samples in histology and cytology to enhance contrast of cellular structures |
| Textile Industry | Natural dye (historical use) | Combined with mordants (e.g., alum, iron salts) for dyeing natural fibers such as cotton and silk, yielding blue-black to purplish-black shades |
| Analytical Chemistry | Metal ion indicator (e.g., for aluminum, lead, beryllium) | Leveraged for colorimetric analysis or endpoint indication in titrations, based on formation of colored complexes with specific metal ions |
