· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Health Hazards
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]:
· May cause toxic effects if inhaled or absorbed through skin.
Hazards SummaryA moderate skin irritant; Intraperitoneal LD50 (mouse) = 800 mg/kg; [RTECS] Safe when used as a flavoring agent in food; [JECFA] A skin and strong eye irritant; [Alfa Aesar MSDS]
DOT ID and Guide2385 129
Reactive GroupEsters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reactivity AlertsHighly Flammable
Reactivity Profile
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.
