25154-54-5 Usage
Description
Dinitrobenzene is a group of three isomeric compounds, namely 1,2-, 1,3-, and 1,4-dinitrobenzenes, which are solid at room temperature and are typically found in a non-aqueous solvent or carrier. These compounds are toxic by skin absorption, and their exposure to heat or shock may lead to explosive decomposition, producing toxic oxides of nitrogen during combustion.
Uses
Used in Chemical Industry:
Dinitrobenzene is used as a chemical intermediate for the production of various compounds, including dyes, explosives, and celluloid.
Used in Dye Production:
Dinitrobenzene serves as a crucial intermediate in the synthesis of dyestuffs, contributing to the development of a wide range of colors and pigments for various applications.
Used in Explosive Manufacturing:
Due to its explosive properties, dinitrobenzene is utilized as a component in the manufacturing of explosives, enhancing their performance and effectiveness in various applications.
Used in Celluloid Production:
Dinitrobenzene is also employed in the production of celluloid, a plastic material derived from cellulose that has been used historically in the film industry and other applications.
Reactivity Profile
dinitrobenzene may react vigorously with oxidizing materials. Reaction with nitric acid (nitration) leads to a mixture of trinitrobenzenes possessing high-explosive properties [Urbanski, 1967, vol. 3, p. 290]. If heat and reaction conditions of the nitration are not controlled, detonation comparable to that of TNT may occur [Anon., J. R. Inst. Chem., 1960, 84, p. 451]. A mixture of 1,3-dinitrobenzene with tetranitromethane can be highly explosive [Urbanski, 1964, vol. 1, 592]. 1,2-dinitrobenzene is a severe explosion hazard when shocked or exposed to heat or flame.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
Suspected carcinogen.
A poison. When heated to decomposition it
emits toxic fumes of NOx. See also oDINITROBENZENE.
Carcinogenicity
In vitro studies show that m-DNB is mutagenic
in Salmonella typhimurium.
The 2003 ACGIH threshold limit valuetime-
weighted average (TLV-TWA) for all
isomers of dinitrobenzene is 0.15 ppm (1.0mg/
m3) with a notation for skin absorption.
Check Digit Verification of cas no
The CAS Registry Mumber 25154-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,5 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25154-54:
(7*2)+(6*5)+(5*1)+(4*5)+(3*4)+(2*5)+(1*4)=95
95 % 10 = 5
So 25154-54-5 is a valid CAS Registry Number.
