3,3',4,4',5,5'-hexahydroxy-2,2'-methylenedi(benzoic acid), also known as phloroglucinol carboxylic acid or 2,2'-methylenebis(3,4,5-trihydroxybenzoic acid), is a complex organic compound with the molecular formula C14H12O9. It is a white crystalline solid that is soluble in water and various organic solvents. 3,3',4,4',5,5'-hexahydroxy-2,2'-methylenedi(benzoic acid) is derived from phloroglucinol, a trihydroxybenzene, and features two benzoic acid moieties connected by a methylene bridge. It is an important intermediate in the synthesis of various natural products, pharmaceuticals, and polymers due to its unique structure and reactivity. The compound has been used in the preparation of resins, dyes, and other specialty chemicals, and it also has potential applications in the field of materials science and medicinal chemistry.
The CAS Registry Mumber 552-21-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 2 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 552-21: (5*5)+(4*5)+(3*2)+(2*2)+(1*1)=56 56 % 10 = 6 So 552-21-6 is a valid CAS Registry Number.
