출처Reported found in boiled beef, beef fat, beer, cacao, Swiss cheese, ground and roasted coffee, roasted filberts, milk fat, dried mushroom, peach, roasted peanuts, heated pork fat, black tea and yogurt. Also reported found in peach, strawberry jam, tomato, wheaten bread, Gruyere cheese, heated butter, cooked beef, white wine, red wine, coffee and Bourbon vanilla.
용도γ-Valerolactone is a naturally occurring chemical found in fruits and is frequently used as a food additive. It can be converted to liquid alkenes which can be used as transportation fuels. γ-Valerolactone is widely used in dye baths (coupling agent), brake fluids, cutting oils, and as solvent for adhesives, insecticides, and lacquers.

γ-Valerolactone has a sweet, herbaceous odor.
GAMMA-VALEROLACTONE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This chemical is incompatible with strong oxidizers. (NTP, 1992). This chemical is incompatible with strong oxidizing agents. It is also incompatible with strong acids, strong bases and strong reducing agents. (NTP, 1992).
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.
SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated 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.
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)
