3,3'-Dihydroxydiphenylurea is an organic compound with the chemical formula C13H12N2O3. It is a white crystalline solid that is soluble in water and various organic solvents. 3,3'-Dihydroxydiphenylurea is primarily used as a flame retardant in various materials, including plastics, textiles, and coatings, due to its ability to char and form a protective layer when exposed to heat. It is also known for its thermal stability and low toxicity, making it a preferred choice in many applications. The compound is synthesized through the reaction of 3,3'-dihydroxybenzidine with urea, and it is characterized by its two hydroxyl groups attached to a diphenylurea backbone, which contributes to its flame-retardant properties.

3746-46-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3746-46-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3746-46:
(6*3)+(5*7)+(4*4)+(3*6)+(2*4)+(1*6)=101
101 % 10 = 1
So 3746-46-1 is a valid CAS Registry Number.
