FLUOROMETHANE Uses

Fluoromethane (CAS NO.593-53-3) is used as chemical reagents, organic intermediates, fine chemicals, pharmaceutical research and development.

FLUOROMETHANE Production

Halogenated aliphatic compounds, such as METHYL FLUORIDE, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. The prolonged mixing of halogenated solvents with metallic or other azides may cause the slow formation of explosive azides, for example methylene chloride and sodium azide.

FLUOROMETHANE Consensus Reports

Reported in EPA TSCA Inventory.

FLUOROMETHANE Safety Profile

Narcotic in high concentrations. Acts as a simple asphyxiant. Burns with evolution of hydrogen fluoride. The flame is about as colorless as that of alcohol. When heated to decomposition it emits toxic fumes of F⁻.Safety information of Fluoromethane (CAS NO.593-53-3):

FLUOROMETHANE Standards and Recommendations

OSHA PEL: TWA 2.5 mg(F)/m³
ACGIH TLV: TWA 2.5 mg(F)/m³; BEI: 3 mg/g creatinine of fluorides in urine prior to shift; 10 mg/g creatinine of fluorides in urine at end of shift.
NIOSH REL: (Fluorides, Inorganic) TWA 2.5 mg(F)/m³

FLUOROMETHANE Specification

It is a colorless flammable gas which is heavier than air. METHYL FLUORIDE has an agreeable ether-like odor. METHYL FLUORIDE is narcotic in high concentrations. METHYL FLUORIDE burns with evolution of hydrogen fluoride. The flame is colorless, similar to alcohol. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.
