Potassium pyrocatecholate, also known as potassium 3,4-dihydroxybenzoate, is a chemical compound with the formula C7H5KO4. It is a potassium salt derived from pyrocatechol, which is a dihydroxybenzene isomer. This white crystalline solid is soluble in water and is commonly used as a reducing agent in various chemical reactions. Potassium pyrocatecholate plays a significant role in the synthesis of pharmaceuticals, dyes, and other organic compounds, as well as in analytical chemistry for the determination of metal ions. Its ability to act as a reducing agent stems from the presence of two hydroxyl groups on the benzene ring, which can donate electrons in redox reactions.
The CAS Registry Mumber 5633-97-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,3 and 3 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5633-97: (6*5)+(5*6)+(4*3)+(3*3)+(2*9)+(1*7)=106 106 % 10 = 6 So 5633-97-6 is a valid CAS Registry Number.
