Hazard and Precautionary Statements (GHS)

2-methylheptane-2-thiol Chemical Properties,Usage,Production

General Description

A straw-colored liquid with a strong, obnoxious odor. Lethal by inhalation of even small amounts of vapor. Lethal by skin absorption. Skin and eye irritant. Decomposes at high temperatures to form toxic sulfur oxides and flammable hydrogen sulfide. Less dense than water. Flash point 115°F. Used as a lubricant additive and in polymer modification.

Air & Water Reactions

Flammable.

Reactivity Profile

Organosulfides, such as 2-methylheptane-2-thiol, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.

Health Hazard

TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
