Basic Violet 14 CAS: 632-99-5
Histological & Biological Uses: Basic fuchsin is widely applied in biological research, botanical analysis, and microbiological testing, such as nucleic acid identification and the detection of *Mycobacterium tuberculosis*.
Tissue Staining Effect: This dye can effectively stain collagen, elastic fibers, and multiple tissue samples, making it essential for histologic research and microbial identification.
Solubility Properties: Basic fuchsin dissolves well in both water and ethanol solutions, supporting flexible preparation of staining reagents for different laboratory scenarios.
Storage Stability: When stored away from light and under suitable pH conditions, basic fuchsin retains stable staining performance, ensuring reliable results in diagnostic and experimental applications.
This group includes aniline-based colorants, often referred to as coal‑tar derivatives, which include a wide variety of types with extensive industrial and laboratory uses.
One major drawback is their tendency to break down under light exposure, especially noticeable in dyes such as aniline blue and triarylmethane compounds like brilliant green and methyl green.
Preparing solutions of these colorants demands precise pH adjustment and shielding from UV light. When stored properly, these coloring agents can retain their color stability for several years with no significant fading or degradation.
