1-o-Tolylbiguanide

1-o-Tolylbiguanide (CAS 93-69-6) is a biguanide-class amine compound also known under the trade names Aliant, Sopanox, and Eponoc B. It carries no assigned E-code and is classified under HS code 29252900. The molecular formula is C9H13N5.

In rubber compounding, 1-o-Tolylbiguanide functions as a secondary accelerator, activating sulfur-based vulcanization systems to improve crosslink density and reduce cure times. It is also used in polymer processing where controlled amine-driven curing is required, particularly in specialty elastomer formulations where precise network formation is critical.

This product is supplied as a white to off-white powder or crystalline solid and falls under REACH registration requirements for European procurement. Buyers should confirm supplier SDS documentation and purity grade prior to ordering. Standard packaging formats vary by supplier; bulk and smaller technical-grade quantities are typically available on request.
