3-(Methylthio)propionaldehyde Chemical Properties,Uses,Production

Chemical Properties

CLEAR COLOURLESS LIQUID

Uses

3-Methylthiopropionaldehyde is a synthetic flavoring agent that is a colorless to light yellow liquid with an intense meat odor. it polymerizes with age and is stable in a 50% alcohol solution. it should be stored in glass containers. it is used at low concentrations for meat and broth flavors for applications in meats and condiments at 3 ppm and in baked goods and beverages at 0.5 ppm.

General Description

A colorless to amber liquid with an extremely foul and persistent odor. Slightly soluble in water and denser than water. Contact may slightly irritate skin, eyes and mucous membranes. Moderately toxic. Used as a food additive.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

Organosulfides, such as 3-(Methylthio)propionaldehyde, 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

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits toxic vapors of SOx.
