Usage

General Description

2,6-dinitro-p-toluidine, also known as DINPT, is a chemical compound commonly used in the production of dyes and pigments. It is a yellow to orange crystalline solid with a slightly sweet odor and is highly stable and non-combustible. DINPT is considered to be toxic and a potential carcinogen, with harmful effects on the respiratory and central nervous systems. Exposure to this chemical can occur through inhalation, ingestion, or skin contact, and it is important to handle and store it with caution. DINPT is classified as a hazardous substance and should be used and disposed of in accordance with safety regulations to minimize potential health risks.

Ethyl acetate as a pro-reducing agent in an one-pot reductive deamination of nitroanilines

The reductive deamination of various nitro-substituted anilines by the new method (20% H2SO4/NaNO2/ethyl acetate, Method 1) was studied and compared that with a similar procedure previously developed by Pare et al. (i.e., concentrated H2SO4/NaNO2/ethanol, Method 2) for the dediazonization of 4-methyl-2,6-dinitroaniline. The deaminated products derived from the mononitro-substituted anilines were obtained in good-to-high yield by Method 1 depending upon the position of the nitro group to the amino function. The higher yield of the de-aminated products was observed from the substituted meta-nitroanilines. Method 1 was more suitable for the deamination of 3-nitroanilines. Method 2 was more favorable for the de-amination of denitro-substituted anilines than that for the mononitroanilines. Ethyl acetate was more suitable for the reductive deamination of mononitroanilines, while ethanol was more appropriate for dinitroanilines.

Method for inhibiting the growth of tobacco suckers

The growth of tobacco suckers in tobacco plants is inhibited by applying to the tobacco plants an effective amount of a substituted 2,6-dinitroaniline alone or in combination with a surfactant.
