Aethyl-<4-nitro-phenyl>-α-methoxy-benzyl-phosphonat, also known as ethyl 4-nitrophenyl α-methoxybenzylphosphonate, is a chemical compound with the molecular formula C16H18NO5P. It is a derivative of phosphonic acid, featuring a phosphonate group attached to a benzyl moiety, which in turn is connected to a 4-nitrophenyl group. The α-methoxybenzyl group provides additional steric hindrance and electronic effects, which can influence the compound's reactivity and properties. Aethyl-<4-nitro-phenyl>-α-methoxy-benzyl-phosphonat is often used in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals, due to its potential to act as a precursor for the synthesis of various biologically active molecules. Its structure allows for further functionalization and modification, making it a versatile building block in the field of chemical research and development.
The CAS Registry Mumber 1098-01-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 8 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1098-01: (6*1)+(5*0)+(4*9)+(3*8)+(2*0)+(1*1)=67 67 % 10 = 7 So 1098-01-7 is a valid CAS Registry Number.
