Abstract
The present invention provides a crosslinking agent which can improve crosslinked fluoroelastomer high-temperature vapor resistance and a crosslinked fluoroelastomer having improved high-temperature vapor resistance. The present invention provides a compound having a structure represented by the following formula (1) (in the formula, R1 to R6 are each a hydrogen atom, a substituent, or a leaving group, and two or more of R1 to R6 are leaving groups; Ra to Rc are each a hydrogen atom or a substituent; and n is an integer from 2 to 5).
