α-Chlor-3-nitro-4-hydroxy-acetophenon, also known as 4-hydroxy-3-nitroacetophenone, is an organic compound with the chemical formula C8H6ClNO3. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. α-Chlor-3-nitro-4-hydroxy-acetophenon is characterized by the presence of a chloro group (-Cl) at the alpha position, a nitro group (-NO2) at the 3rd position, and a hydroxyl group (-OH) at the 4th position on the acetophenone backbone. It is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of dyes and pigments. Due to its reactivity, it is important to handle α-Chlor-3-nitro-4-hydroxy-acetophenon with care, as it can be sensitive to heat and light, and may decompose to form potentially hazardous byproducts.
The CAS Registry Mumber 89894-06-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,9 and 4 respectively; the second part has 2 digits, 0 and 6 respectively. Calculate Digit Verification of CAS Registry Number 89894-06: (7*8)+(6*9)+(5*8)+(4*9)+(3*4)+(2*0)+(1*6)=204 204 % 10 = 4 So 89894-06-4 is a valid CAS Registry Number.
