It is one isomer of six with this formula. It is a white solid although commercial samples are often yellow-tan. It is prepared by hydrogenation of 2,4-dinitrotoluene using a nickel catalyst. Commercial samples often contain up to 20% of the 2,6-isomer.[2] It is mainly used as a precursor to toluene diisocyanate, a precursor to polyurethane. Its reaction with benzenediazonium chloride gives the cationic azo dye Basic Orange 1. Condensation of 2,4-diaminotoluene with acetaldehyde gives the acridine dye called Basic Yellow 9.[3] References1. ^1 2 {{PGCH|0620}} {{DEFAULTSORT:Diaminotoluene, 2,4-}}2. ^Robert A.
