3-Aminopropionitrile Usage And Synthesis

Chemical Properties

clear colourless to yellow liquid. 3-Aminopropionitrile, [151-18-8], 3-aminopropanenitrile, b-aminopropionitrile, H2N – CH2 – CH2CN, Mr 70.09, bp 185℃ (101.3 kPa), n20D 1.4396, is a colorless liquid which tends to slowly polymerize if stored in the presence of air. 3-Aminopropionitrile is prepared by the reaction of acrylonitrile with ammonia and is mainly used as an intermediate in the manufacture of b-alanine and pantothenic acid [48].

Uses

3-Aminopropionitrile is used for organic synthesis and as pharmaceutical intermediates. As an intermediate used in the manufacture of beta-alanine and pantothenic acid.

Uses

Production of β-alanine and pantothenic acid.

Definition

ChEBI: An aminopropionitrile carrying an amino group at the beta-position.

Safety Profile

Moderately toxic by intraperitoneal route. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. Nitriles usually have cyanide-like effects. See also CYANIDE. Easily oxidized and unstable. A storage hazard; it polymerizes to an explosive yellow solid. When heated to decomposition it emits toxic fumes of CNand NO,. For fire and explosion hazards see CYANIDE.

Metabolism

3-Aminopropionitrile is the compound present in some Lathyms species (Leguminosae), especially sweet-pea seeds (L. odoratus), causing osteolathyrism in man and animals. Although 3-aminopropionitrile is generally present in the fresh plant as the gama-glutamyl derivative, only the free amine is an effective lathyrogen.
Osteolathyrogens cause skeletal deformations due to interference with the cross-linking between polypeptide chains in the connective tissue components, elastin and collagen. This interference is partly due to inhibition of the synthesis of desmosine and isodesmosine, amino acids which effect the cross-linking in elastin. Cross-linking interference of collagen can be prevented in chicks by feed- ing excess calcium.
It is possible that 3-aminopropionitrile is adegradation product of 3-cyano-alanine, although in many plants the latter compound is converted to asparagine and it has not been detected in Lathyms species.
