Overview

3-(aminomethyl)-3,5,5-trimethylcyclohexan-1-amine (CAS 2855-13-2) is a cycloaliphatic diamine compound featuring two primary amine functional groups and multiple methyl substituents. This specialized diamine, with molecular formula C10H22N2 and molecular weight 170.3 g/mol, belongs to the family of cycloaliphatic amines that are valued for their unique structural properties and reactivity profiles. The compound features a cyclohexane ring backbone with two amine groups positioned at the 1 and 3 positions, along with three methyl substituents that provide steric hindrance and influence its chemical behavior. Unlike simpler amines such as phenylmethanamine, this cycloaliphatic structure offers enhanced thermal stability and reduced volatility, making it particularly suitable for demanding industrial applications. The presence of both primary amine groups enables this compound to function as an effective curing agent and cross-linking component in various polymer systems. Its unique molecular architecture, characterized by the sterically hindered trimethyl-substituted cyclohexane ring, provides controlled reactivity that is essential in formulating high-performance materials. The compound exhibits typical properties of aliphatic diamines but with modified kinetics due to its cyclic structure and methyl substitution pattern. Safety considerations are paramount when handling this material, as it is classified under multiple hazard categories including acute toxicity, skin corrosion, eye damage, and skin sensitization. The compound requires careful handling procedures and appropriate personal protective equipment, reflecting its corrosive nature typical of concentrated amine compounds. Primary industrial applications include use as a curing agent for epoxy resins, particularly in coatings and adhesives requiring enhanced chemical resistance, and as an intermediate in the synthesis of specialty polymers and performance chemicals. The compound also finds application in the production of polyamide resins where its unique structure contributes to improved thermal and mechanical properties. OYSI provides reliable access to 3-(aminomethyl)-3,5,5-trimethylcyclohexan-1-amine for European industrial customers requiring consistent quality and technical support.
