Alizarin Red S, identified by CAS number 130-22-3, is a synthetic anthraquinone dye that has carved a significant niche in scientific research due to its unique interaction with calcium ions. Understanding its chemical properties and mechanism of action is fundamental for researchers aiming to leverage its capabilities effectively. This dye, typically appearing as an orange to deep orange powder, exhibits good solubility in water, forming a characteristic yellow-brown solution. Its molecular structure allows it to act as a chelating agent, forming stable complexes with divalent metal cations, most notably calcium.

The primary mechanism through which Alizarin Red S functions in biological contexts involves its chelation with calcium phosphate and calcium carbonate deposits. Upon binding, it forms an insoluble orange-red complex. This reaction is highly specific and sensitive, making it an excellent indicator for the presence and localization of calcium in various biological matrices. In histological staining, this property is exploited to visualize mineralization fronts in bone, cartilage, and other calcified tissues. This makes it an invaluable tool for studying processes like osteogenesis, bone healing, and mineral metabolism, supporting research endeavors that require precise quantitative or qualitative assessment of calcium deposition.
