2-Fluor-5-nitrophenylchloroform, also known as 2-fluoro-5-nitrobenzene chloroformate, is an organic compound with the chemical formula C7H4ClFNO3. It is a derivative of benzene, featuring a fluorine atom at the 2-position, a nitro group at the 5-position, and a chloroformate group attached to the benzene ring. 2-Fluor-5-nitrophenylchloroform is a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique combination of functional groups. It is typically synthesized through the reaction of 2-fluoro-5-nitrophenol with phosgene or a similar chlorocarbonylating agent. The compound is sensitive to moisture and should be handled under anhydrous conditions to prevent hydrolysis. Its reactivity and stability make it a versatile building block in organic synthesis, particularly in the preparation of esters, amides, and other derivatives.
The CAS Registry Mumber 713-20-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 713-20: (5*7)+(4*1)+(3*3)+(2*2)+(1*0)=52 52 % 10 = 2 So 713-20-2 is a valid CAS Registry Number.
