4051-56-3 Usage

General Description

N,N-diphenylbenzamide, also known as benzophenone-3 or oxybenzone, is a chemical compound commonly used as a UV filter in sunscreen and other personal care products. It is known for its ability to absorb and dissipate UV radiation, providing protection against the harmful effects of sun exposure. However, concerns have been raised about the potential health risks associated with N,N-diphenylbenzamide, including hormone disruption and allergic reactions. In response to these concerns, some countries and organizations have restricted or banned the use of this chemical in certain products. Further research is needed to fully understand the potential risks and benefits of N,N-diphenylbenzamide in personal care products.

Check Digit Verification of cas no

The CAS Registry Mumber 4051-56-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4051-56:
(6*4)+(5*0)+(4*5)+(3*1)+(2*5)+(1*6)=63
63 % 10 = 3
So 4051-56-3 is a valid CAS Registry Number.

Enhanced two-photon absorption of novel four-branched chromophore via vibronic coupling

Wang, Deqiang,Wang, Xiaomei,He, Qingguo,Zhou, Maoyi,Rui, Wenwen,Tao, Xutang,Bai, Fenglian,Jiang, Minhua

, p. 5871 - 5876 (2008)

A novel four-branched chromophore TOZ-4 with starburst linker was synthesized and showed two-photon absorption cross-section (δ) as large as 5254 GM, which was principally resulted from vibronic coupling enhancement.

PCl3-mediated transesterification and aminolysis of tert-butyl esters via acid chloride formation

Wu, Xiaofang,Zhou, Lei,Li, Fangshao,Xiao, Jing

, p. 491 - 497 (2021/01/20)

A PCl3-mediated conversion of tert-butyl esters into esters and amides in one-pot under air is developed. This novel protocol is highlighted by the synthesis of skeletons of bioactive molecules and gram-scale reactions. Mechanistic studies revealed that this transformation involves the formation of an acid chloride in situ, which is followed by reactions with alcohols or amines to afford the desired products.

An Environmentally Benign, Catalyst-Free N?C Bond Cleavage/Formation of Primary, Secondary, and Tertiary Unactivated Amides

Kumar, Vishal,Dhawan, Sanjeev,Girase, Pankaj Sanjay,Singh, Parvesh,Karpoormath, Rajshekhar

, p. 5627 - 5639 (2021/11/11)

Herein, we report an operationally simple, cheap, and catalyst-free method for the transamidation of a diverse range of unactivated amides furnishing the desired products in excellent yields. This protocol is environmentally friendly and operates under extremely mild conditions without using any promoter or additives. Significantly, this strategy has been implied in the chemoselective synthesis of a pharmaceutical molecule, paracetamol, on a gram-scale with excellent yield. We anticipate that this universally applicable strategy will be of great interest in drug discovery, biochemistry, and organic synthesis.
