Phosphorofluoridic acid monobutyl ester, also known as n-butyl phosphorofluoridate, is an organophosphorus compound with the chemical formula C4H9FO2P. It is a colorless, oily liquid that is soluble in organic solvents and has a pungent odor. phosphorofluoridic acid monobutyl ester is primarily used as a chemical warfare agent, specifically as a nerve agent, due to its ability to inhibit the enzyme acetylcholinesterase, which is crucial for the proper functioning of the nervous system. Exposure to phosphorofluoridic acid monobutyl ester can lead to severe health effects, including respiratory distress, muscle twitching, and potentially death. It is classified as a Schedule 1 substance in the Chemical Weapons Convention due to its potential use in warfare.
The CAS Registry Mumber 372-03-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 2 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 372-03: (5*3)+(4*7)+(3*2)+(2*0)+(1*3)=52 52 % 10 = 2 So 372-03-2 is a valid CAS Registry Number.
