25154-55-6 Usage
Uses
Used in Chemical Manufacturing:
Nitrophenol is used as a raw material for the production of various chemicals. Its chemical properties, including the presence of three isomers (o-, m-, and p-nitrophenol), make it a versatile compound for synthesizing different chemical products.
Used in Environmental Protection:
Due to its potential environmental hazards, Nitrophenol is also used in efforts to limit its spread and mitigate its impact on the environment. Immediate steps should be taken to prevent its release into the environment, and proper handling and disposal methods are crucial to minimize its ecological footprint.
Used in Research and Development:
The different isomers of Nitrophenol, particularly the p-isomer (4-nitrophenol), are of interest in toxicology and research. Understanding the properties and effects of these isomers can contribute to the development of safer chemicals and processes in the chemical industry.
Used in Combustion Safety:
As a combustible material, Nitrophenol's properties are relevant in the field of combustion safety. Its ignition characteristics and the toxic byproducts produced during burning are important factors to consider when assessing the risks associated with its use and handling.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
Organonitrate compounds, such as Nitrophenol, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups. Phenols do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. 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. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Potential Exposure
(p-isomer): Possible risk of forming
tumors, Suspected reprotoxic hazard. Nitrophenols are used
as intermediates in production of dyes; photochemicals,
pesticides, and pharmaceuticals; in leather tanning.
Shipping
UN1663 Nitrophenols (o-; m-; p-), Hazard
Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Nitrophenols are strong oxidizers. Reacts
violently with combustible and reducing agents. Contact
with potassium hydroxide forms an explosive mixture. May
explode on heating.
Waste Disposal
Controlled incineration-care
must be taken to maintain complete combustion at all
times. Incineration of large quantities may require scrubbers
to control the emission of nitrogen oxides. In accordance
with 40CFR165, follow recommendations for the
disposal of pesticides and pesticide containers. Must be disposed
properly by following package label directions or by
contacting your local or federal environmental control
agency, or by contacting your regional EPA office. Consult
with environmental regulatory agencies for guidance on
acceptable disposal practices. Generators of waste containing
this contaminant (≥100 kg/mo) must conform with
EPA regulations governing storage, transportation, treatment,
and waste disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 25154-55-6 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 25154-55:
(7*2)+(6*5)+(5*1)+(4*5)+(3*4)+(2*5)+(1*5)=96
96 % 10 = 6
So 25154-55-6 is a valid CAS Registry Number.
