Phosphonic difluoride, also known as (1-methylethyl)-, is a chemical compound with the formula C4H9F2OP. It is a colorless liquid at room temperature and is derived from the reaction of phosphorus trifluoride (PF3) with isopropanol (2-propanol). Phosphonic difluoride, (1-methylethyl)- is an important intermediate in the synthesis of various organophosphorus compounds, such as flame retardants, pesticides, and pharmaceuticals. It is also used as a catalyst in the production of certain polymers. Due to its reactivity, it is essential to handle Phosphonic difluoride, (1-methylethyl)- with care, as it can be hazardous and may cause irritation to the eyes, skin, and respiratory system.

677-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 677-42-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 677-42:
(5*6)+(4*7)+(3*7)+(2*4)+(1*2)=89
89 % 10 = 9
So 677-42-9 is a valid CAS Registry Number.
