Special Reports
TOXICOLOGICAL REVIEW OF PHOTOTOXICITY, DERMAL & MEMBRANE IRRITATION CAUSED BY COUMARIN.[GLOXHUBER C, BLOCHING H; TOXICOLOGIC PROPERTIES OF FLUORESCENT WHITENING AGENTS; WINEK CL & SHANOR SP (ED), TOXICOLOGY ANNUAL, VOL 3. NY: MARCEL DEKKER, INC, 1979, PP 171-203]
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.
Sicherheit und Schutzausrüstung
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Nonfire Spill Response
SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Personal Protective Equipment (PPE)
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Chemie und Industrie
Verwendung und Herstellung
Uses
Used as an optical brightener (textile, detergent, plastics, and varnish/lacquer industries) and as an invisible marking agent; Also used in coatings (paper, labels, and book covers) and as a laser dye; [HSDB] Coumarins are used as fluorescent dyes and also as laser dyes. Fluorescent dyes not only absorb light; they also emit light to produce very bright colors. They are used to dye textile fibers, plastics, inks, and to make pigments for paints and lacquers.
