1,3-Dimercaptopropane Chemical Properties,Usage,Production

Application

Used as a usual flavor.

Toxicity

GRAS(FEMA)

Usage restriction

FEMA：baked goods, meat product, soups, snack foods, sauces, candy and sugar cream: 0.2mg/kg.

Chemical Properties

1,3-Propanedithiol has a sulfur, meaty odor. FEMA indicates that total dithiol added to any food should not exceed 1.0 ppm.

Chemical Properties

colourless to slightly yellow liquid

Occurrence

Reported found in cooked or boiled beef.

Uses

1,3-Propanedithiol is used as a reagent in the preparation of thioketals and thioacetals. It acts as a flavoring agent. It is used as a precursor in the synthesis of cyclic dithioacetal (1,3-dithiane) derivatives of carbonyl compounds. It is involved in the preparation of diiron propanedithiolate hexacarbonyl by reacting reaction with triiron dodecacarbonyl. Further, it is used for the protection of aldehydes and ketones through their reversible formation of dithianes. In addition to this, it reacts with metal ions to form chelate rings.

Definition

ChEBI: A dithiol that is propane substituted by thiol groups at positions 1 ans 3.

General Description

Clear orange oil with a disagreeable odor.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Organosulfides, such as 1,3-Dimercaptopropane, 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. 1,3-Dimercaptopropane may react with oxidizers, bases, reducing agents and alkali metals.

Fire Hazard

1,3-Dimercaptopropane is combustible.
