Chemical Properties
grey powder
Uses
The compound has been used as an intermediate for dyes, to
some extent in preparing certain polyamide fibers, and as a
curing agent for polyurethane.
Uses
2,6-Dichloro-1,4-phenylenediamine is an aromatic amine that can be found in azo dyes. It was studied for potential mutagenic and toxic properties.
Preparation
The chromophore Preparation: Will 2,6-Dichioro-4-nitroaniline reduction.
Production Methods
2,6-Dichloro-p-PDA is not currently produced in the United
States; the sole manufacturer ceased production in 1978. It is
a chemical intermediate used as a polyurethane curative, and
as a monomer in the manufacture of polyamide fiber.
Definition
ChEBI: 2,6-Dichloro-para-phenylenediamine is a dichlorobenzene.
