Description
Fuchsine basic (C.I. 42510) is a classical triarylmethane dye supplied for microscopy applications, with CAS number 632-99-5 and empirical formula C₂₀H₂₀N₃Cl. Its molar mass is 337,85 g/mol and the material shows a density of 0,6 g/cm³ together with a flash point of 220 °C. The dye is Categories such as pH indicators and analytical chemicals reflect its established role in microscopy staining and related colour reactions. This grade from manufacturer Carl ROTH carries EG number 211-189-6 and is described specifically for microscopy use. Laboratories value the defined identity and physical data when preparing reproducible staining baths or reference solutions. The compact glass packaging supports controlled dispensing and storage within routine laboratory workflows while preserving the integrity of the solid dye.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Fuchsine basic (C.I. 42510), for microscopy, 50 g, glass
What is this article?
Fuchsine basic (C.I. 42510), for microscopy, 50 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Microscopy stains & staining solutions, inside Dyes, stains & indicators, in Lab chemicals.
A microscopy stain binds a structure so it can be seen: haematoxylin on nuclei, eosin on cytoplasm, Gram reagents on a bacterial wall. A ready solution and a dry dye to be dissolved are different articles. The method names the stain. A substitute dye is a different method.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
Which category should I open next?
