49742-68-9 Usage
General Description
2-(2-hydroxy-4-pyrrolidinylbenzoyl)benzoic acid, also known as BPB, is a synthetic compound that belongs to the family of benzophenones. It is commonly used as a UV filter in sunscreens and cosmetic products due to its ability to absorb and block harmful UV rays. BPB has a molecular structure that allows it to effectively protect the skin from sun damage by absorbing UVB and UVA radiation. Additionally, it has shown anti-inflammatory and antioxidant properties, making it a valuable ingredient in skin care products. However, there are concerns about its potential to disrupt endocrine function and its bioaccumulation in the environment, which has led to regulatory restrictions on its use in certain regions.
Check Digit Verification of cas no
The CAS Registry Mumber 49742-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,4 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49742-68:
(7*4)+(6*9)+(5*7)+(4*4)+(3*2)+(2*6)+(1*8)=159
159 % 10 = 9
So 49742-68-9 is a valid CAS Registry Number.

Synthesis of Aminobenzopyranoxanthenes with Nitrogen-Containing Fused Rings
Fukino, Natsumi,Kamino, Shinichiro,Takahashi, Minami,Sawada, Daisuke
, p. 13626 - 13631 (2017)
An efficient and practical method for the synthesis of a variety of aminobenzopyranoxanthenes (ABPXs) with different nitrogen-containing fused rings was developed. On the basis of the mechanistic studies of the formation of the xanthene framework, the presented methodology was developed to facilitate access to previously inaccessible asymmetric ABPXs.
