4-Hydroxy-3-t-butyl-pivalophenon, also known as 4-hydroxy-3-t-butyl-4'-methylphenyl phenyl ketone, is a white crystalline compound with the chemical formula C16H22O2. It is a derivative of pivalophenon, characterized by the presence of a hydroxyl group at the 4-position and a t-butyl group at the 3-position. This organic compound is often used as a spectrophotometric reagent for the determination of trace amounts of iron in various samples, such as water, beverages, and food products. The reaction between 4-hydroxy-3-t-butyl-pivalophenon and iron ions results in the formation of a red-colored complex, which can be quantified by measuring the absorbance at a specific wavelength. This method is known for its high sensitivity and selectivity, making it a valuable tool in analytical chemistry.
The CAS Registry Mumber 5384-64-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,8 and 4 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5384-64: (6*5)+(5*3)+(4*8)+(3*4)+(2*6)+(1*4)=105 105 % 10 = 5 So 5384-64-5 is a valid CAS Registry Number.
