Carboxyphenyl, also known as 4-hydroxybenzoic acid, is an organic compound with the chemical formula C7H6O3. It is a white crystalline solid that is soluble in water, alcohol, and ether. carboxyphenyl- is an aromatic carboxylic acid, featuring a hydroxyl group (-OH) attached to the para position of a benzene ring, with a carboxyl group (-COOH) at the same position. Carboxyphenyl is widely used in various applications, including pharmaceuticals, as a preservative and antimicrobial agent, and in the synthesis of other chemicals. Its ability to form complexes with metal ions also makes it useful in analytical chemistry for the detection and quantification of certain metals.
The CAS Registry Mumber 4294-92-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,9 and 4 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4294-92: (6*4)+(5*2)+(4*9)+(3*4)+(2*9)+(1*2)=102 102 % 10 = 2 So 4294-92-2 is a valid CAS Registry Number.
