Hazard InformationBack Directory
[General Description]

Brown liquid. Insoluble in water.
[Reactivity Profile]

METHYL TRIFLUOROMETHANE SULFONATE(333-27-7) is sensitive to heat. . 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.
[Air & Water Reactions]

Highly flammable. Insoluble in water.
[Health Hazard]

ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes.
[Fire Hazard]

This chemical is combustible.
[Chemical Properties]

Methyl trifluoromethanesulfonate (methyl triflate) [333-27-7] M 164.1, b 97 -97.5o/736mm, 9 9o/~760mm, 100-102o/~760mm, d 4 1.496, n D 1.3238. It is a strong methylating agent but is corrosive and POISONOUS. Fractionate it carefully and collecting the middle fraction (use an efficient fume cupboard) and keep away from moisture. It is a POWERFUL ALKYLATING AGENT and a strong IRRITANT.
