Phosphorous acid, 1-methylethyl diphenyl ester, also known as diphenyl isopropyl phosphonate, is an organophosphorus compound with the chemical formula C15H17O2P. It is a colorless to pale yellow liquid that is soluble in organic solvents and has a molecular weight of 262.27 g/mol. Phosphorous acid, 1-methylethyl diphenyl ester is primarily used as a flame retardant, plasticizer, and stabilizing agent in various industrial applications, including the production of plastics, rubber, and resins. It is also employed as an intermediate in the synthesis of other organophosphorus compounds. Due to its potential health and environmental risks, proper handling and disposal procedures should be followed when working with phosphorous acid, 1-methylethyl diphenyl ester.

7330-17-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7330-17-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7330-17:
(6*7)+(5*3)+(4*3)+(3*0)+(2*1)+(1*7)=78
78 % 10 = 8
So 7330-17-8 is a valid CAS Registry Number.

Reactions of 6-iodogalactosides with either methyl or isopropyl diphenyl phosphite lead to diphenylphosphoryl derivatives; these can be converted by ester exchange into dibenzylphosphoryl derivatives, which are convenient precursors of carbohydrate phosphonic acids.
