What is N-METHYL-P-TOLUIDINE?

Chemical properties

CLEAR YELLOW TO BROWN LIQUID

General Description

N-Methyl-p-toluidine is an aromatic secondary amine. It forms social isomers when encapsulated with a molecule of chloroform or benzene in a cylindrical capsule. 2-amino-4,6-dichloropyrimidine-5-carbaldehyde undergoes mono-amination with N-methyl-p-toluidine to form a precursor for the preparation of pyrazolo[3,4-d]pyrimidines. It annelates with dimethyl acetylenedicarboxylate via formation of toluidine radical cation intermediate.
