2-Diethylphosphinoyl-propionsaeure-ethylester, also known as ethyl 2-diethylphosphonopropionate, is an organophosphorus compound with the chemical formula C7H15O4P. It is a colorless liquid with a molecular weight of 200.16 g/mol. 2-Diethylphosphinoyl-propionsaeure-ethylester is characterized by the presence of a diethylphosphinoyl group (P(O)(OEt)2) attached to a propionic acid moiety, which is further esterified with ethanol. It is synthesized through the reaction of diethyl phosphite with ethyl 2-bromopropionate. Ethyl 2-diethylphosphonopropionate is used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a ligand in transition metal-catalyzed reactions. Due to its phosphorus content, it may have potential applications in the development of pesticides or as a chemical warfare agent, although its specific use in these areas is not well-documented.

7751-88-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7751-88-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7751-88:
(6*7)+(5*7)+(4*5)+(3*1)+(2*8)+(1*8)=124
124 % 10 = 4
So 7751-88-4 is a valid CAS Registry Number.
