Acid fuchsin is a water-soluble, non-toxic, acidic dye that is used in histology to stain connective tissue and mucous membranes. It is used as an indicator for calcium in the presence of acid phosphatase. Acid fuchsin can be detected by light microscopy when it is stained on a section of tissue or cells. This dye can be used with immunocytochemistry or cytogenetics to assess the morphology of cells and tissues. The staining intensity varies according to the concentration of the acid fuchsin solution, which can be quantified by measuring the absorbance at 510 nm. A reference range for this measurement would be 0.1 - 1 μg/ml (10 - 100 μM).

C.I. Acid Blue 3 is a synthetic, water-soluble dye that has been used in analytical chemistry for the detection of metal hydroxides and other metal ions. The dye can be activated by radiation or by heating to produce a bright blue color that is stable under acidic conditions. C.I. Acid Blue 3 has been shown to cause toxicity in animals, and may have potential carcinogenic effects in humans due to its ability to cross the blood-brain barrier and accumulate in the brain. The molecular weight of this compound is approximately 464 g/mol and it has a molecular formula of C 18 H 20 N 2 NaO 7 S 2 .
