o-Nitro-benzhydrylbromid, also known as 2-nitrobenzhydryl bromide, is a chemical compound with the molecular formula C13H10BrNO2. It is a derivative of benzhydryl bromide, featuring a nitro group (-NO2) at the ortho position (2nd position) of the benzene ring. This yellow crystalline solid is primarily used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and other chemical compounds. Due to its reactivity, o-nitro-benzhydrylbromid is sensitive to light and moisture, and it is typically stored under controlled conditions to maintain its stability.
The CAS Registry Mumber 1022-05-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1022-05: (6*1)+(5*0)+(4*2)+(3*2)+(2*0)+(1*5)=25 25 % 10 = 5 So 1022-05-5 is a valid CAS Registry Number.
