1433-00-7 Usage
Chemical structure
1,1'-Biphenyl, 4,4'-bis(phenylsulfonyl)is composed of two benzene rings linked together by a single carbon-carbon bond and substituted with sulfonyl groups at the 4,4' positions.
Application
It is commonly used as a high-performance polymer additive to improve the thermal and mechanical properties of polymers such as polyethersulfone (PES) and polyetherimide (PEI).
Heat and flame resistance
The presence of the sulfonyl groups imparts heat and flame resistance to the resulting polymer.
Chemical resistance
The sulfonyl groups also provide chemical resistance to the resulting polymer.
Use in production
1,1'-Biphenyl, 4,4'-bis(phenylsulfonyl)is also used in the production of specialty chemicals and in organic synthesis.
Safety precautions
It should be handled with care due to its potential irritant and harmful effects if inhaled, ingested, or in contact with the skin.
Potential hazards
Inhalation, ingestion, and skin contact can cause irritation and harm to the body.
Handling
Proper handling and storage procedures should be followed to minimize the risk of exposure to this chemical compound.
Check Digit Verification of cas no
The CAS Registry Mumber 1433-00-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1433-00:
(6*1)+(5*4)+(4*3)+(3*3)+(2*0)+(1*0)=47
47 % 10 = 7
So 1433-00-7 is a valid CAS Registry Number.
