Description
Reichardt's dye is a well-established solvatochromic indicator compound identified by CAS number 10081-39-7 and the empirical formula C₄₁H₂₉NO. With a molar mass of 551,68 g/mol, it provides a clearly defined molecular basis for quantitative and spectroscopic laboratory applications. The dye is widely employed to probe solvent polarity, medium effects, and microenvironment characterisation through pronounced shifts in its charge-transfer absorption band. Specification data from manufacturer Carl ROTH include CAS registry number, empirical formula, and molar mass, enabling reliable identity confirmation and documentation. This presentation is intended for trained users who require a classical betaine dye for polarity scales, solvent studies, or related photophysical investigations under standard laboratory conditions.

Questions about Reichardt's dye, 1 g
What is this article?
Reichardt's dye, 1 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
