Diisopropyl N-benzoylphosphoramidate, also known as DFP, is a potent organophosphorus compound that acts as a nerve agent and irreversible acetylcholinesterase inhibitor. It is a colorless, oily liquid with a slight odor and is highly toxic through inhalation, ingestion, or skin contact. DFP was originally developed as a chemical warfare agent, but its use is now prohibited under international law. It can cause severe health effects, including respiratory failure, seizures, and death, by disrupting the nervous system's ability to transmit signals. Due to its high toxicity and potential for misuse, DFP is strictly regulated and is not used for any legitimate commercial or industrial purposes.

Check Digit Verification of cas no

The CAS Registry Mumber 3808-08-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,0 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3808-08:
(6*3)+(5*8)+(4*0)+(3*8)+(2*0)+(1*8)=90
90 % 10 = 0
So 3808-08-0 is a valid CAS Registry Number.

Synthesis of tetraphenylphosphonium (thio)phosphorylthiobenzamides and hydrolytic degradation to Ph3P=O, H2S and phosphoryl(thio)benzamides: A route for crystal design of PhC(X)NHP(O)(OiPr) 2 (X=S, O)

Reactions of the sodium salts of PhC(S)NHP(Y)(OiPr)2 (Y=S, HLI; O, HLII) with PPh4Br in 96% aqueous EtOH leads to the corresponding compounds PPh4LI,II. The structures of these compounds we

REACTIONS OF N-PHOSPHORYLATED AMIDES AND THIOAMIDES WITH ALKYL HALIDES

Zabirov, N. G.,Shamsevaleev, F. M.,Cherkasov, R. A.

, p. 876 - 881 (2007/10/02)

N-Phosphorylated thioamides and also their alkali-metal salts are easily alkylated by alkyl halides at the sulfur atom of the thiocarbonyl group, and in this process the reactivities of the alkyl halides decrease in the sequence: primary>secondary>tertiary. N-Phosphorylated amides do not react with alkyl halides, whereas their alkali-metal salts form easily hydrolyzable products of alkylation at the sulfur or oxygen atom of the P=X group of the monophosphazene structure. Alkylation reactions of N-phosphorylated amides and thioamides take only one course: The formation of products of alkylation at the nitrogen atom is not observed.
