Applications

 

1. Biological Staining and Microscopy

Extensively used in histology and microbiology as a biological stain.

Stains acidic cell components (e.g., nuclei, bacteria, mitochondria), helping visualize microscopic structures clearly.

Applied in blood film staining (e.g., Giemsa stain formulations).

2. Medical and Pharmaceutical Uses

Used as a medication for treating:

Methemoglobinemia (by reducing methemoglobin to hemoglobin)

Ifosfamide-induced neurotoxicity

Urinary tract antiseptic

Investigated for potential use in Alzheimer's disease and malaria treatment (antiparasitic action).

3. Aquaculture and Veterinary Use

Serves as a fungicide and antibacterial agent in fish farming.

Used to treat fish eggs and live fish against parasitic or fungal infections.

4. Textile and Paper Industry

Functions as a cationic dye for dyeing silk, wool, and paper.

Commonly used in school laboratories for paper-based dye experiments.

5. Redox Indicator in Chemistry

Acts as a redox indicator in titrations and analytical chemistry.

Used in biological experiments involving electron transport chains (e.g., demonstrating mitochondrial respiration).
