4,4'-bis-(2-pyridinethiocarboxamido)-biphenyl, also known as 4,4'-BPTC, is a chemical compound with the molecular formula C20H14N4S2. It is a white crystalline solid that is soluble in organic solvents such as dimethyl sulfoxide (DMSO) and dimethylformamide (DMF). 4,4'-bis-(2-pyridinethiocarboxamido)-biphenyl is primarily used as a flame retardant in various materials, including plastics, textiles, and coatings. 4,4'-BPTC works by releasing sulfur and nitrogen when exposed to heat, which helps to interrupt the combustion process. It is also known for its high thermal stability and low toxicity, making it a preferred choice in many applications. However, it is important to note that the use of 4,4'-BPTC and other flame retardants is subject to regulatory considerations due to potential environmental and health concerns.

2177-26-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2177-26-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.Calculate Digit Verification of CAS Registry Number 2177-26:
(6*2)+(5*1)+(4*7)+(3*7)+(2*2)+(1*6)=76
76 % 10 = 6
So 2177-26-6 is a valid CAS Registry Number.
