16965-75-6 Usage
General Description
Phosphonic acid, (chlorophenylmethyl)-, dimethyl ester is a chemical compound with the molecular formula C9H13ClO3P. It is a clear to straw colored liquid that is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. Phosphonic acid, (chlorophenylmethyl)-, dimethyl ester is also used as a chelating agent in metal ion sequestration and as a stabilizer in plastics and polymers. It is considered to be a hazardous substance and should be handled with care due to its potential for acute toxicity and skin irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 16965-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,6 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16965-75:
(7*1)+(6*6)+(5*9)+(4*6)+(3*5)+(2*7)+(1*5)=146
146 % 10 = 6
So 16965-75-6 is a valid CAS Registry Number.

Nucleophilic substitution reactions of benzyl- and diphenylmethylphosphonamidic chlorides with amines: Competition between the usual SN2(P) mechanism and elimination-addition with an alkylideneoxophosphorane (phosphene) intermediate
Harger, Martin J. P.
, p. 41 - 47 (2007/10/03)
The substitution reaction of PhCH2P(O)(NMe2)Cl with Me2NH or Et2NH in CHCI3 is very sensitive to the bulk of the nucleophile (≥ 200 times slower with Et2NH), affords only the product derive
