Description
Brilliant Green (C.I. 42040) is a triarylmethane dye supplied for microscopy and related laboratory staining work. It is identified by CAS number 633-03-4 and empirical formula C₂₇H₃₄N₂O₄S, with a molar mass of 482,64 g/mol. This grade is The EG number is 211-190-1. Intended for microscopy use, the dye supports histological and microbiological staining protocols where Brilliant Green or C.I. 42040 is required. Offered by manufacturer Carl ROTH, it integrates readily into analytical-chemical and indicator reagent ranges in research, teaching, and quality laboratories. Defined molar mass supports reproducible concentration control when formulating working solutions. Suitable for bright-field microscopy, differential staining schemes, and general dye chemistry applications that specify Brilliant Green in a convenient laboratory pack size.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Brilliant Green (C.I. 42040), for microscopy, 25 g, glass
What is this article?
Brilliant Green (C.I. 42040), for microscopy, 25 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.
