An amine of formula (I) in a curing agent for epoxy resins, a curing agent for epoxy resins containing the amine of formula (I) and resultant epoxy resin compositions which can be used particularly as low-emission room-temperature-curing epoxy resin coatings demonstrating good workability, rapid curing, a high degree of hardness and high surface quality. The amine of formula (I) is low-odour, can be handled well at room temperature even without dilution, and can be produced at high purity in a simple process.
