Description
Leuco crystal violet is a high-purity analytical dye supplied at min. 98 %, p.a., for laboratory staining and related chemical applications. It carries CAS number 603-48-5 and EG nr. 210-043-9, with empirical formula C₂₅H₃₁N₃ and a molar mass of 373,53 g/mol. Physical data include a density of 1,141 g/cm³ and a boiling point of 227,8 °C, supporting method setup and safety assessment. Classified among dyes for biological applications, it suits research and routine laboratory environments that require defined purity. The material is available from manufacturer Carl ROTH in a compact glass unit suited to analytical benches. UN number 3077 is associated with transport classification where applicable. Consistent identity parameters help laboratories maintain traceable reagent records and reproducible staining or detection procedures without expanding pack sizes beyond small-scale needs.

Questions about Leuco crystal violet, min. 98 %, p.a., 5 g, glass
What is this article?
Leuco crystal violet, min. 98 %, p.a., 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.
