Benzoic acid, 4,4'-(1,3-propanediyl)bis-, also known as 4,4'-sec-butylbenzopimaric acid or 4,4'-(1,3-propanediyl)bisbenzoic acid, is a white crystalline solid with the chemical formula C17H18O4. It is a dimeric form of benzoic acid, where two benzoic acid molecules are linked by a 1,3-propanediyl (trimethylene) bridge. Benzoic acid, 4,4'-(1,3-propanediyl)bis- is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is also known for its potential applications in the field of materials science, such as in the development of high-performance polymers and coatings. The compound is characterized by its melting point of around 230-232°C and is soluble in common organic solvents like ethanol, acetone, and dichloromethane.
The CAS Registry Mumber 5140-05-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5140-05: (6*5)+(5*1)+(4*4)+(3*0)+(2*0)+(1*5)=56 56 % 10 = 6 So 5140-05-6 is a valid CAS Registry Number.
