14Benzenedimethanamine

1,4-Benzenedimethanamine, also known as p-xylylenediamine, is an aromatic diamine with the chemical formula C8H10N2. It consists of a benzene ring substituted at the para positions by two methanamine (-CH2NH2) groups, giving the structural motif C6H4(CH2NH2)2. The compound is typically encountered as a solid at room temperature and is used in polymer chemistry as a diamine curing agent or as a monomer in the synthesis of polyurethanes, polyimides, and related materials. In epoxy systems, it can act as a hardener or chain extender, improving thermal and mechanical properties. It is also used as an intermediate in the manufacture of specialty polymers and dyes.

Safety and handling: 1,4-Benzenedimethanamine is a corrosive material and may cause irritation to skin, eyes, and the respiratory tract. It should be handled with appropriate personal protective equipment, in a well-ventilated area or under fume control. Avoid inhalation of dust or vapors and contact with skin or eyes. In case of exposure, consult safety data sheets and seek medical attention.

Storage and procurement: it is typically supplied as technical grade or in solution with solvents. It is stored in sealed containers away from heat and oxidizers, in accordance with local regulations for diamines. Environmental considerations emphasize minimizing releases and avoiding aquatic exposure.
