4,4'-dinitro-benzhydrol, also known as 4,4'-dinitrobenzhydrol or DNBH, is an organic compound with the chemical formula C13H10N2O4. It is a yellow crystalline solid that is derived from benzhydrol, a central benzene ring with two hydroxyl groups attached to it. The "4,4'-dinitro" part of the name indicates that there are nitro groups (-NO2) attached to the 4th carbon atoms of the benzene ring. 4,4'-dinitro-benzhydrol is used as a chemical intermediate in the synthesis of various dyes and pharmaceuticals, and it is also known for its potential applications in the field of materials science, such as in the development of high-energy materials and as a component in the production of certain types of explosives. Due to its reactivity and potential hazards, it is important to handle 4,4'-dinitro-benzhydrol with care and in accordance with proper safety protocols.
The CAS Registry Mumber 1033-25-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,3 and 3 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1033-25: (6*1)+(5*0)+(4*3)+(3*3)+(2*2)+(1*5)=36 36 % 10 = 6 So 1033-25-6 is a valid CAS Registry Number.
