Product Name: 7-Diethylamino-4-methylcoumarin
CAS No.:91-44-1
Molecular Formula: C14H17NO2
Molecular Weight: 231.29 g/mol
Physical Properties
Appearance: White powder.
Melting Point: 69-71 °C.
Boiling Point: 243 °C (6.5 mmHg).
Density: 1.122 g/cm³.
Refractive Index: 1.5300.
Solubility: Insoluble in water; slightly soluble in hot water; soluble in organic solvents (e.g., ethanol, acetone).
Chemical Properties
Exhibits typical chemical properties of coumarin compounds:
The diethylamino and methyl groups can undergo substitution reactions (e.g., nucleophilic substitution on the amino group).
The coumarin core is prone to hydrolysis, addition reactions, and other characteristic transformations under acidic or basic conditions.
Strong fluorescence emission due to the conjugated π-electron system in the coumarin ring.
Applications
Laser Dye Industry:
Known as "Coumarin-1," it is a widely used laser dye with high conversion efficiency and a broad tuning range (4400-4800 Å).
Applied in tunable dye lasers for ultraviolet, visible, and infrared spectral research, such as isotope separation and dynamic studies of chemical reactions.
Fluorescent Whitening Agent:
Used for whitening synthetic fibers (nylon, polyester, aramid) and paper products, enhancing brightness through fluorescence emission.
Medical and Pharmaceutical Research:
Derivatives are studied for developing photo-responsive anticancer agents (e.g., introducing the MDAC moiety into quinone methide derivatives to create H2O2-targeted DNA cross-linkers).
