Overview

4-[(4-aminophenyl)methyl]aniline (CAS 101-77-9) is an aromatic diamine compound with two primary amine groups connected via a methylene bridge. This organic chemical compound, also known by its EC number 202-974-4, belongs to the family of aromatic diamines characterized by its molecular formula C13H14N2 and molecular weight of 198.26 g/mol. The substance features two benzene rings, each bearing an amino group, linked through a methylene (-CH2-) bridge, creating a symmetrical structure that imparts specific chemical reactivity and industrial utility. Due to its dual amine functionality, 4-[(4-aminophenyl)methyl]aniline exhibits significant chemical reactivity, particularly in condensation and polymerization reactions. However, this compound requires careful handling as it is classified under multiple hazard categories including carcinogenicity (Carc. 1B), mutagenicity (Muta. 2), and specific target organ toxicity (STOT SE 1, STOT RE 2). The substance also demonstrates skin sensitization properties (Skin Sens. 1) and poses aquatic environmental concerns (Aquatic Chronic 2), necessitating appropriate safety measures during storage, handling, and transportation under ADR class 6.1. In industrial applications, this aromatic diamine serves primarily as an intermediate in polymer synthesis, particularly in the production of polyurethanes and epoxy resins where its bifunctional nature enables cross-linking reactions. The compound also finds use in specialty chemical manufacturing and as a building block for advanced materials. While structurally different from compounds like benzene-1,3-diol, both substances share applications in polymer chemistry due to their reactive functional groups. OYSI maintains availability of 4-[(4-aminophenyl)methyl]aniline for qualified industrial customers across Europe, ensuring compliance with all relevant safety and regulatory requirements.
