Histochemistry relies on a precise palette of stains to illuminate the complex landscape of cellular and tissue structures. Among these, Solvent Black 3, identified by CAS number 4197-25-5, plays a significant role, particularly in the visualization of lipids and fats. For researchers and technicians needing to buy this specialized dye, understanding its characteristics and applications is fundamental.

Solvent Black 3 is classified as an azo dye and typically presents as a fine black powder. Its molecular formula, C29H24N6, and a molecular weight of 456.54 are indicative of its organic nature. A key characteristic for its application is its solubility in organic solvents, which facilitates its penetration into lipid-rich cellular components. The dye exhibits good heat resistance, with a specified heat resisting property up to 230°C, and a melting point around 120°C, contributing to its utility in various laboratory protocols.

In histochemistry, Solvent Black 3 is primarily employed as a lysochrome, meaning it is fat-soluble. This property makes it exceptionally useful for staining neutral triglycerides and other lipids within frozen tissue sections. It is also effective in staining certain lipoproteins in paraffin sections. Its applications extend to distinguishing between paraffin and animal fats, staining myelin sheaths in nervous tissue, and visualizing leukocyte granules and Golgi apparatus. The ability to clearly delineate these structures makes it an indispensable reagent for many research endeavors.

The versatility of Solvent Black 3 also lends itself to other applications, such as enhancing latent fingerprints in forensic analysis, further underscoring its importance across scientific disciplines. For laboratories performing detailed tissue analysis, sourcing a high-quality Solvent Black 3 is paramount to achieving accurate and reproducible results.
