[1,1'-Biphenyl]tetracarboxylic acid, also known as BTA or 4,4'-(1,1'-biphenyl)-4,4'-dicarboxylic acid, is a white crystalline organic compound with the chemical formula C16H12O8. It is a derivative of biphenyl, featuring two benzene rings connected by a single bond, with four carboxylic acid groups attached to the terminal carbon atoms of each benzene ring. BTA is a versatile chemical intermediate used in the synthesis of various polymers, dyes, and pharmaceuticals. It is also known for its chelating properties, making it useful in the formulation of metalworking fluids and as a corrosion inhibitor. The compound is typically synthesized through the oxidation of biphenyl or by the condensation of phthalic anhydride with benzene-1,2-diol. BTA is characterized by its high melting point, around 360°C, and is insoluble in water but soluble in organic solvents such as ethanol and acetone.

69066-95-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69066-95-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,6 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 69066-95:
(7*6)+(6*9)+(5*0)+(4*6)+(3*6)+(2*9)+(1*5)=161
161 % 10 = 1
So 69066-95-1 is a valid CAS Registry Number.
