Salpetersaeure-<3,3,3-trifluor-1-(4-nitro-phenyl)-propylester>, also known as 3,3,3-trifluoro-1-(4-nitrophenyl)propan-1-yl nitrate or 4-nitrophenyl 3,3,3-trifluoropyruvate, is a chemical compound with the molecular formula C9H7F3NO5. It is a derivative of nitric acid, featuring a trifluoromethyl group and a 4-nitrophenyl group attached to a propyl ester. Salpetersaeure-<3,3,3-trifluor-1-(4-nitro-phenyl)-propylester> is primarily used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. Due to its potential reactivity and the presence of nitro and ester functional groups, it should be handled with care, following proper safety protocols.
The CAS Registry Mumber 2557-19-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 7 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2557-19: (6*2)+(5*5)+(4*5)+(3*7)+(2*1)+(1*9)=89 89 % 10 = 9 So 2557-19-9 is a valid CAS Registry Number.
