Description
Diethyl safranine (C.I. 50206) is a cationic safranine dye supplied for microscopy applications, identified by CAS number 4569-86-2 and the empirical formula C₂₂H₂₃ClN₄. With a molar mass of 378,91 g/mol, this coloured reagent is used in histological and cytological staining workflows where safranine-type dyes support contrast and structural visualisation under the microscope. The material is Diethyl safranine from manufacturer Carl ROTH provides a clearly defined dye identity (C.I. 50206) for routine and specialised microscopy protocols in research and teaching laboratories. Its defined molecular composition supports reproducible preparation of working stains when handled according to standard laboratory practice. The compact glass unit is practical for controlled dispensing and storage within chemical inventories dedicated to microscopy dyes and related biological stains.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Diethyl safranine (C.I. 50206), for microscopy, 1 g, glass
What is this article?
Diethyl safranine (C.I. 50206), for microscopy, 1 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?
