653605-35-7 Usage
Uses
Used in Cosmetic Industry:
Benzoic acid, 4-(sulfooxy)-, 1-(phenylmethyl) ester, ammonium salt is used as an impurity in the synthesis of p-Salicylic Acid 4-Sulfate for its role as a urine metabolite of Methylated paraben. Methylated paraben serves as an antimicrobial agent, ensuring the preservation and safety of cosmetic products by preventing the growth of harmful microorganisms.
In the synthesis process, the presence of Benzoic acid, 4-(sulfooxy)-, 1-(phenylmethyl) ester, ammonium salt may affect the purity and quality of the final product, p-Salicylic Acid 4-Sulfate. Therefore, it is essential to monitor and control the levels of this impurity to maintain the effectiveness and safety of the antimicrobial agent used in the cosmetic industry.
Check Digit Verification of cas no
The CAS Registry Mumber 653605-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,3,6,0 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 653605-35:
(8*6)+(7*5)+(6*3)+(5*6)+(4*0)+(3*5)+(2*3)+(1*5)=157
157 % 10 = 7
So 653605-35-7 is a valid CAS Registry Number.
