Collection: Coumarin Dyes

Coumarin Dyes — a collection of fluorescent coumarin derivatives with various amino and heteroaromatic substituents, known as the Coumarin dye group with distinctive numbering such as Coumarin 102, 314, and 6H. Its conjugated structure produces fluorescence emission in the blue to green wavelength range.

Coumarin dyes are used by photonics and optical materials researchers as laser dyes, fluorescence sensitizers in OLED displays, and fluorescence probes in spectroscopy and imaging studies. Bromomethyl-coumarin derivatives are also used as fluorescent labeling reagents for chemical conjugation in functional materials research.

Example products in this collection: TCI B5008 1256259-14-9 4-(Bromomethyl)-7-(diethylamino)coumarin, TCI C2267 41267-76-9 Coumarin 102, TCI B4257 155306-71-1 Coumarin 545T, TCI C2268 55804-66-5 Coumarin 314, TCI B2111 27425-55-4 3-(2-Benzimidazolyl)-7-(diethylamino)coumarin, TCI C2836 58336-35-9 Coumarin 6H, TCI B2088 38215-36-0 3-(2-Benzothiazolyl)-7-(diethylamino)coumarin, TCI C2837 41044-12-6 7-(Diethylamino)-3-(1-methyl-2-benzimidazolyl)coumarin.
