7-Diethylamino-4-methylcoumarin Chemical Properties,Uses,Production

Chemical Properties

light tan powder

Uses

7-(Diethylamino)-4-methylcoumarin, is potentially useful as a laser dye.

Uses

Optical bleach in textile industry, in coatings for paper, labels, book covers, etc.; to lighten plastics, resins, varnishes, and lacquers; invisible marking agent.

Definition

ChEBI: Coumarin 460 is a member of 7-aminocoumarins. It has a role as a fluorochrome.

General Description

Light tan grains. Gives bright blue-white fluorescence in very dilute solutions.

Reactivity Profile

7-Diethylamino-4-methylcoumarin is a lactone (behaves as an ester) and an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
