General Description
Bis(2-naphthoyl)methane, also known as α,α′-Bis(naphthoyl)biphenyl or 2,2'-Bis(naphthalen-2-yl)benzophenone, is a chemical compound with the molecular formula C26H18O. It is a yellow to brownish crystalline solid that is insoluble in water but soluble in organic solvents. Bis(2-naphthoyl)methane is primarily used as an ultraviolet (UV) light absorber and is often added to plastics, polymers, and coatings to protect them from UV radiation and prevent photo-degradation. It is also used as a photo-initiator in the production of adhesives, inks, and other materials, as well as in the synthesis of organic dyes and pigments. Additionally, it has potential applications in the field of organic electronics and as a component in some sunscreen formulations. Bis(2-naphthoyl)methane should be handled with care, as it may cause skin and eye irritation and could pose health risks if inhaled or ingested.
Check Digit Verification of cas no
The CAS Registry Mumber 51583-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,8 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51583-97:
(7*5)+(6*1)+(5*5)+(4*8)+(3*3)+(2*9)+(1*7)=132
132 % 10 = 2
So 51583-97-2 is a valid CAS Registry Number.

Influence of the Localization of the Excitation Energy on the Photochemistry of α,β-Epoxy Ketones
Hallet, Philippe,Muzart, Jacques,Pete, Jean-Piere
, p. 4275 - 4279 (2007/10/02)
Depending on the localization of the energy, photolysis of α-epoxy ketones excited in their triplet state leads to β-diketones, α-diketones, or fragmentation products.Absorption spectra of ylide intermediates and phosphorescence spectra of α-epoxy ketones are reported.
