2,2,3,3-Tetrakis(trifluoromethyl)oxirane, also known as tetrafluoropropene oxide or TFPO, is a colorless, highly reactive, and toxic chemical compound with the molecular formula C5F8O. It is an oxirane derivative, characterized by the presence of an epoxide ring (a three-membered ring containing an oxygen atom). The compound is widely used as a curing agent for epoxy resins, particularly in the production of high-performance composite materials, due to its ability to cross-link the polymer chains and improve the material's mechanical properties. However, it is also known for its potential health risks, as it can cause irritation to the eyes, skin, and respiratory system, and may have long-term effects on the liver and kidneys. Due to its hazardous nature, proper safety measures and handling procedures must be followed when working with 2,2,3,3-tetrakis(trifluoromethyl)oxirane.
The CAS Registry Mumber 1708-78-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 8 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1708-78: (6*1)+(5*7)+(4*0)+(3*8)+(2*7)+(1*8)=87 87 % 10 = 7 So 1708-78-7 is a valid CAS Registry Number.
