Sudan Black, alcoholic, is primarily used for staining tissue samples in medical and histological diagnostics. Thanks to the pronounced affinity of this dye for lipophilic structures, it is particularly suitable for staining lipids and fatty substances. In combination with ethanol and water, a ready-to-use solution is obtained that allows high penetration into tissue samples, leading to meaningful results.

Chemically, Sudan Black is an organic dye whose specific interactions with lipids are based on the lipophilicity of the dye. This allows selective staining of lipids in biological samples.

With the use of this solution, high contrast visualization of lipids in tissue sections can be achieved. This visual differentiation is of great benefit in histological analysis and contributes significantly to the accuracy of medical diagnoses.
