Description
Coumarin VIS-463 TM-BQZ benzimidazole is a coumarin-based dye with CAS number 155306-73-3 and empirical formula C₂₆H₂₇N₃O₂. It has a molar mass of 413,52 g/mol and an absorption maximum of 463 nm in methanol (MeOH), placing it in the visible range for optical and fluorescence-related laboratory work. 812-707-9, this benzimidazole-substituted coumarin supports dye screening, spectral calibration, and method development in organic photochemistry. The defined absorption maximum and molecular parameters help set solvent choice, path length, and concentration for UV/Vis measurements. Research groups working on coumarin chromophores, visible-light absorbers, or structure–property comparisons can use the material as a characterised reference compound. quantity is practical for analytical series, small synthetic trials, and documentation of spectral behaviour under controlled laboratory conditions.
This article is part of Bases & alkalis, in Acids & bases.

Questions about Coumarin VIS-463 TM-BQZ Benzimidazole, Absorption maximum (MeOH) = 463 nm, 1 g
What is this article?
Coumarin VIS-463 TM-BQZ Benzimidazole, Absorption maximum (MeOH) = 463 nm, 1 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
