Diethylphosphoramidic difluoride, also known as DEPF or (EtO)2P(O)F2, is an organophosphorus compound that serves as a valuable intermediate in the synthesis of various agrochemicals, pharmaceuticals, and other chemical products. It is a colorless, volatile liquid with a pungent odor and is highly reactive due to the presence of the phosphorus-fluorine bond. DEPF is widely used in the production of pesticides, such as organophosphate insecticides, and plays a crucial role in the formation of various esters and amides through nucleophilic substitution reactions. Due to its reactivity and potential toxicity, it is essential to handle DEPF with proper safety precautions and in controlled environments.

359-94-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 359-94-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 359-94:
(5*3)+(4*5)+(3*9)+(2*9)+(1*4)=84
84 % 10 = 4
So 359-94-4 is a valid CAS Registry Number.

Interaction of α,α-difluoroazides with trivalent phosphorus compounds and triphenylantimony

Lermontov,Polivanova,Shkavrov

experimental part, p. 1646 - 1651 (2011/02/18)

α,α-Difluoroazides react with triphenylantimony and various compounds of trivalent phosphorus according to the oxidative fluorination scheme. In the case of trivalent phosphorus compound the primary products are phosphazenes, phosphazides or difluorophosphoranes that may undergo further transformations to the corresponding fluorine derivatives of pentavalent phosphorus.
