N-Fluoracetyl-N'-benzoyl-hydrazin, also known as NFA-BH or simply NFA, is a chemical compound with the molecular formula C14H11FN2O2. It is a derivative of hydrazine, featuring a fluoroacetyl group and a benzoyl group attached to the nitrogen atoms. NFA is primarily used as a reagent in organic synthesis, particularly for the fluorination of various substrates. It is known for its ability to transfer a fluorine atom to a wide range of organic compounds, making it a valuable tool in the synthesis of fluorinated molecules, which have applications in pharmaceuticals, agrochemicals, and materials science. The compound is also recognized for its potential use in the detection of certain enzymes due to its ability to form stable adducts with them. NFA is a white crystalline solid that is sensitive to moisture and should be handled with care due to its reactivity.
The CAS Registry Mumber 2145-88-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 5 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2145-88: (6*2)+(5*1)+(4*4)+(3*5)+(2*8)+(1*8)=72 72 % 10 = 2 So 2145-88-2 is a valid CAS Registry Number.
