Description
Patent blue V sodium salt (C.I. 42051:2) is an extra pure dye reagent for laboratory and analytical applications. Identified by CAS number 20262-76-4 and the empirical formula C₂₇H₃₁N₂O₇S₂Na, this sodium salt of the triarylmethane colourant has a molar mass of 582,66 g/mol. Physical data include a density of 0,455 g/cm³, a flash point of 168,6 °C and a boiling point above 300 °C. The material is supplied in a 10 g glass pack that supports accurate weighing and controlled handling in research and quality-control settings. Applications typically encompass staining procedures, colour marking and dye chemistry studies where a defined Colour Index designation is essential. Available from manufacturer Carl ROTH, the product is listed under EG number 243-654-4 and is intended for users who require an extra pure grade of Patent blue V sodium salt. Its documented physicochemical parameters and convenient pack size make it a practical choice for laboratories that maintain dye and indicator inventories for routine experimental work.

Questions about Patent blue V sodium salt (C.I. 42051:2)
What is this article?
Patent blue V sodium salt (C.I. 42051:2) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dyes & pigments, inside Dyes, stains & indicators, in Lab chemicals.
A dye dissolves. A pigment is a particle dispersed in a medium. On this shelf they are the colouring substances used as reagents or as markers, specified by Colour Index name or by structure where it is known. The same common name can hide two constitutions.
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 Dyes & pigments. The catalogue is Lab chemicals.
