Guanidine nitrate

Guanidine nitrate (CAS 506-93-4), also known as guanidinium nitrate or by the synonym NSC 7295, is the nitrate salt of guanidine. It is an inorganic salt classified under Salts & Minerals and carries no assigned E-code, reflecting its use outside direct food additive applications.

In pyrotechnics and gas generant formulations, guanidine nitrate functions as an oxidiser-fuel combination within a single molecule, enabling controlled rapid gas release for airbag inflators and mining initiators. In flame retardant systems, it acts as a nitrogen-releasing agent that promotes char formation and dilutes combustible gases during thermal decomposition.

Guanidine nitrate is supplied in technical and pharmaceutical-grade forms, with procurement subject to REACH registration requirements within the European Economic Area. Due to its classification as an oxidising solid, packaging and transport comply with ADR regulations. Buyers should confirm grade specifications and documentation requirements at the point of inquiry.
