Urea, N-nitroso-N-[2-[(tetrahydro-2H-pyran-2-yl)oxy]ethyl]-, also known as THPC-N-NO, is a chemical compound characterized by its nitrogen-nitrogen double bond, which is typical of nitroso compounds. It is synthesized from urea and nitrosating agents and is widely recognized for its role as a flame retardant and smoke suppressant in various materials such as textiles, plastics, and coatings. THPC-N-NO's ability to inhibit combustion and reduce the emission of toxic fumes during a fire contributes significantly to the fire safety of products in which it is incorporated. Despite its utility, THPC-N-NO has faced scrutiny due to potential health and environmental impacts, leading to regulatory measures in some regions.

57331-63-2 Usage

Uses

Used in Textile Industry:
Urea, N-nitroso-N-[2-[(tetrahydro-2H-pyran-2-yl)oxy]ethyl]is used as a flame retardant and smoke suppressant for enhancing the fire safety of textiles. It helps in reducing the risk of fire-related accidents and the spread of flames in case of a fire incident.
Used in Plastics Industry:
In the plastics industry, Urea, N-nitroso-N-[2-[(tetrahydro-2H-pyran-2-yl)oxy]ethyl]is utilized as an additive to improve the fire resistance of plastic materials. This is crucial for applications where plastics are used in close proximity to potential ignition sources or where the consequences of a fire would be particularly severe.
Used in Coatings Industry:
Urea, N-nitroso-N-[2-[(tetrahydro-2H-pyran-2-yl)oxy]ethyl]is employed as a component in fire-resistant coatings. These coatings are applied to various surfaces to provide an additional layer of protection against fire, thereby slowing down the spread of flames and reducing smoke production.
It is important to consider the regulatory status and potential health and environmental implications when using THPC-N-NO in these applications, ensuring compliance with local laws and safety standards.

Check Digit Verification of cas no

The CAS Registry Mumber 57331-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,3 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57331-63:
(7*5)+(6*7)+(5*3)+(4*3)+(3*1)+(2*6)+(1*3)=122
122 % 10 = 2
So 57331-63-2 is a valid CAS Registry Number.
