97-02-9 Usage

Description

2,4-Dinitroaniline, with the molecular formula C6H5N3O4, is a yellow crystalline solid that serves as a versatile intermediate in the chemical industry. Its chemical structure, featuring two nitro groups at the 2nd and 4th positions on the benzene ring, endows it with unique properties that make it suitable for various applications.

Uses

Used in Dye and Pigment Production:
2,4-Dinitroaniline is used as an intermediate in the synthesis of certain dyes and pigments. Its chemical reactivity allows for the creation of a range of colorants that are used in various industries, including textiles, plastics, and printing inks.
Used in Pharmaceutical Synthesis:
In the pharmaceutical industry, 2,4-Dinitroaniline is utilized as a precursor for the synthesis of various organic compounds. Its ability to undergo a range of chemical reactions makes it a valuable building block for the development of new drugs and pharmaceutical agents.
Safety Considerations:
Due to its toxic nature, 2,4-Dinitroaniline poses a risk if ingested or inhaled and can cause irritation to the skin and eyes. As a result, it is classified as a hazardous substance, and appropriate safety measures should be taken during its handling, storage, and use. This includes wearing protective equipment, such as gloves and goggles, and following proper disposal procedures to minimize exposure and environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 97-02-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 97-02:
(4*9)+(3*7)+(2*0)+(1*2)=59
59 % 10 = 9
So 97-02-9 is a valid CAS Registry Number.

One-pot synthesis of N-substituted diaza[12]annulenes

Yamaguchi, Isao,Gobara, Yoshiaki,Sato, Moriyuki

, p. 4279 - 4281 (2006)

(Chemical Equation Presented) N-Substituted diaza[12]annulenes are obtained by one -pot reaction of n-(2,4-dinitrophenyl)pyridinium chloride with amines in moderate to high yields. The 1H NMR spectrum reveals that diamagnetic ring current is generated in the diaza[12]annulene ring. The N-substituted diaza[12]annulenes are electrochemically active in solution.

Hydride Transfer from Cyclohexadienyl Anions: The Reaction between the Hydride Meisenheimer Adduct of 2,4-dinitroaniline and 1,3,5-trinitrobenzene

Atkins, Paul J.,Gold, Victor,Wassef, Wasfy N.

, p. 1197 - 1198 (1983)

The hydride Meisenheimer adduct of 2,4-dinitroaniline transfers hydride to 1,3,5-trinitrobenzene to form its corresponding hydride Meisenheimer adduct.The reaction is practically irreversible.In dilute solution in dimethyl sulphoxide it exhibits second-order kinetics and the observation of several sharp isosbestic points shows that it occurs without formation of any detectable intermediate species.

Paragraph 0018-0022, (2021/08/07)

The invention relates to the field of pharmaceutical chemicals, and discloses a preparation method of 2,4-dinitroaniline. The preparation method comprises the following four steps: (1) adding 2,4-dinitrochlorobenzene and urea in a molar ratio of 1: (1.5-2.5) into a reaction kettle; (2) adding an ethanol water solvent into the reaction kettle, wherein the ethanol concentration of the ethanol water solvent is 30%-100%, and the adding amount of the ethanol water solvent is 1.5-3 times of the mass of the 2,4-dinitrochlorobenzene; (3) heating the reaction kettle to 110-135 DEG C, controlling a pressure to be 0.2-0.3 MPa, and carrying out a heat preservation reaction for 3-5 hours; and (4) after the reaction is finished, centrifugally filtering and washing a reaction product to obtain the 2,4-dinitroaniline. According to the invention, the urea is used for replacing ammonia water and ammonia gas, and relatively low reaction temperature and pressure are adopted, so the explosion risk of ammonia gas volatilization is avoided, production cost is reduced, product purity and yield are improved, and the method has remarkable safety benefit, economic benefit and quality benefit.

A highly efficient heterogeneous copper-catalysed cascade reaction of aryl iodides with acetamidine hydrochloride leading to primary arylamines

Huang, Xue,Xiao, Ruian,You, Chongren,Yan, Tao,Cai, Mingzhong

, p. 315 - 320 (2017/06/19)

A highly efficient heterogeneous copper-catalysed cascade reaction of aryl iodides with acetamidine hydrochloride was achieved in DMF in the presence of 10 mol% of an MCM-41-immobilised L-proline-copper(I) complex (MCM-41-L-proline-CuI) with Cs2CO3 as base, yielding a variety of primary arylamines in good to excellent yields. The new heterogeneous copper complex can be easily prepared from commercially readily available and inexpensive reagents, recovered by a simple filtration of the reaction solution and used at least seven more times without any decrease in activity.
