Description
Brilliant Violet 5R is a synthetic dye reagent with CAS number 12226-38-9 and empirical formula C₂₀H₁₆N₃Na₃O₁₅S₄. Its molar mass is 735,58 g/mol, supporting precise formulation work in analytical and preparative laboratory settings. Physical handling benefits from the compact glass pack, which helps protect the solid during storage and dispensing on the bench. This grade is offered from manufacturer Carl ROTH for routine laboratory use within chemical catalogues covering dyes and related specialties. Researchers can integrate Brilliant Violet 5R into method development, comparative dye studies, or teaching demonstrations that call for a characterised violet colourant. The combination of known molecular formula, molar mass, and convenient pack size supports reproducible weighing and solution preparation. Use standard laboratory practice for solids when transferring and dissolving the product.
This article belongs on Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Brilliant Violet 5R, 5 g, glass
What is this article?
Brilliant Violet 5R, 5 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?
The category is Dyes, stains & indicators. The sub-category is Microscopy stains & staining solutions. The catalogue is Lab chemicals.
Shelves beside this one are Fluorescent dyes & labels and Dyes & pigments.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
