25109-57-3 Usage
General Description
1,2-Dibromo-3-butanone, also known as dibromoketone or DBK, is a chemical compound used as a disinfectant and water treatment agent. It is a highly reactive molecule that is capable of forming covalent bonds with proteins, nucleic acids, and other biomolecules. Due to its ability to crosslink and modify biological molecules, 1,2-Dibromo-3-butanone is often used as a biocide in water treatment applications to control microbial growth. However, its high reactivity and potential for adverse health effects have raised concerns about its environmental and human health impact. In addition to its use in water treatment, 1,2-Dibromo-3-butanone is also being investigated for its potential application as a chemotherapeutic agent for cancer treatment, due to its ability to selectively target and modify certain cancer cells.
Check Digit Verification of cas no
The CAS Registry Mumber 25109-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,0 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25109-57:
(7*2)+(6*5)+(5*1)+(4*0)+(3*9)+(2*5)+(1*7)=93
93 % 10 = 3
So 25109-57-3 is a valid CAS Registry Number.

Three bacteriorhodopsins with ring-didemethylated 6-s-locked chromophores and their properties
Groesbeek, M.,Galen, A. J. J. van,Ippel, J. H.,Berden, J. A.,Lugtenburg, J.
, p. 237 - 246 (2007/10/02)
Three novel, 6-s-locked rigidified retinals, racemic all-E 1,5-didemethyl-8,16-methanoretinal, all-E, 1,1-didemethyl-8,18-methanoretinal and all-E 8a,18-didehydro-1,1-didemethyl-8,18-methanoretinal were prepared in good yield in high purity on a 100-mg scale.For the preparation of the key intermediate in the synthesis of 1,5-didemethyl-8,16-methanoretinal, reductive cyanation of an unsaturated cyanohydrin to the corresponding conjugated nitrile was accomplished using triethylsilane and trifluoroacetic acid.The three locked retinals interact with bacterioopsin to form bacteriorhodopsin with about the same rate as the native chromophore.This work proves that steric interaction of the 1,1-dimethyl group in the chromophore is an important factor in binding to bacterioopsin.
