Difluorophenylmethyl isocyanate, also known as 2,6-difluorophenyl isocyanate, is an organic compound with the chemical formula C7H3F2NO. It is a colorless to pale yellow liquid that is sensitive to light and moisture. Difluorophenylmethyl isocyanate is a derivative of phenyl isocyanate, featuring two fluorine atoms attached to the phenyl ring, which significantly alter its chemical properties. Difluorophenylmethyl isocyanate is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is typically handled under controlled conditions to prevent unwanted reactions.

1644-16-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1644-16-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1644-16:
(6*1)+(5*6)+(4*4)+(3*4)+(2*1)+(1*6)=72
72 % 10 = 2
So 1644-16-2 is a valid CAS Registry Number.

Syntheses of New Aromatic Compounds with Fluorinated Side Chains and their Chemical Reactivity

Haas, Alois,Spitzer, Martin,Lieb, Max

, p. 1329 - 1340 (2007/10/02)

The syntheses of a wide range of aromatic compounds of the type p-Y-C6H4CF2X(4-13) are described, and the chemical behavior of these compounds as a function of substituent Y is investigated .Analogously the pyridine derivatives 15, 17, and 18 were synthesized and characterized.From a correlation of the 19F-NMR data of these compounds with the Hammett constant of Y, participation of C-F ?-back-donation is seen as the cause for an observed shift of the 19F signals to lower field.
