Overview
Propanedinitrile (CAS 109-77-3) is an organic nitrile compound with two cyano functional groups and significant toxicity properties. This dinitrile compound, also known by its systematic IUPAC name propanedinitrile, represents an important building block in organic synthesis and industrial chemistry. With the molecular formula C3H2N2 and a molecular mass of 66.06 g/mol, this colorless crystalline solid features two nitrile groups attached to a central methylene carbon, creating a highly reactive and versatile chemical intermediate. The compound exhibits significant safety concerns, classified under multiple acute toxicity categories (Acute Tox. 3) for oral, dermal, and inhalation exposure routes. Its environmental profile shows aquatic toxicity with both acute and chronic effects on aquatic organisms, reflected in its GHS06 and GHS09 pictograms indicating both toxicity and environmental hazards. Transportation regulations classify it under ADR Class 6.1 as a toxic substance, requiring appropriate handling protocols and safety measures during storage and transport. In industrial applications, propanedinitrile serves primarily as a chemical intermediate in pharmaceutical synthesis, polymer production, and specialty chemical manufacturing. Its dual nitrile functionality makes it particularly valuable for creating complex molecular structures through various synthetic pathways. The compound also finds use in the production of certain agricultural chemicals, though with different applications than related compounds such as 2,4-dinitro-6-pentan-2-ylphenol which is used in pesticide formulations. OYSI maintains reliable supply chains for propanedinitrile, ensuring consistent availability for European industrial customers requiring this specialized chemical intermediate.
