3-(Methylthio)propionaldehyde(Cas 3268-49-3) Usage

Preparation

By transamination and decarboxylation of various amino acids; by oxidation of the alcohol

Synthesis Reference(s)

Journal of the American Chemical Society, 70, p. 1450, 1948 DOI: 10.1021/ja01184a044

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.

Flammability and Explosibility

Notclassified

Biochem/physiol Actions

Taste at 0.5-1ppm

Safety Profile

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

Aroma threshold values

Aroma characteristics at 0.1%: vegetable oil, creamy tomato, potato skin and French fry, yeasty, bready, limburger cheese with a savory meaty brothy nuance

Taste threshold values

Taste characteristics at 5 ppb to 5 ppm: potato, musty, tomato, mold ripened cheeses, onion, beefy brothy, egg, seafood and vegetative nuances.

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.
