Meta Toluene Diamine (MTD)
Meta-Toluene Diamine (MTD) is a dark brown to black aromatic solid produced by Karoon Petrochemical Company (Iran). This compound is primarily used as an intermediate in the production of toluene diisocyanate (TDI), a key component in polyurethane foams, elastomers, adhesives, and coatings.
With its aromatic amine structure, MTD exhibits high chemical reactivity, making it an essential raw material in the polyurethane industry. It also serves as a curing agent for epoxy resins, and as a chemical intermediate in the manufacture of dyes, corrosion inhibitors, and specialty polymers.
Meta-Toluene Diamine is typically handled in solid form at room temperature but can be melted for easier processing. The product is highly reactive, toxic, and should be handled under controlled industrial conditions with appropriate safety and ventilation systems.

Meta-Toluene Diamine (MTD) is an organic aromatic compound with the chemical formula C₆H₃CH₃(NH₂)₂. It is composed primarily of two positional isomers — 2,4-Diaminotoluene and 2,6-Diaminotoluene — typically present in an 80 ± 1 / 20 ± 1 ratio, respectively.
This mixture of isomers provides high reactivity and chemical stability, making MTD a critical intermediate in the production of toluene diisocyanate (TDI). The compound’s molecular structure, which contains both amine functional groups and a methyl-substituted aromatic ring, allows it to react efficiently with phosgene and other reagents in polyurethane synthesis.
Meta-Toluene Diamine is widely recognized for its role in producing flexible and rigid polyurethane foams, elastomers, adhesives, and industrial coatings. It also finds limited application as a curing agent and chemical intermediate in the manufacture of dyes, epoxy systems, and specialty chemicals.
