4-Methyl-2,4-bis(4-hydroxyphenyl)pent-1-ene (MBP) is a metabolite of bisphenol A (BPA). [1] MBP has potent estrogenic activity in vitro and in vivo , up to thousandfold stronger than BPA. [ 2 ] It may also play a role in neuronal cell apoptosis [ 3 ] and may increase risk for several forms of cancer.
Butyrophenone is an organic compound with the formula C 6 H 5 C(O)C 3 H 7. It is a colorless liquid. It is a colorless liquid. The butyrophenone structure—a ketone flanked by a phenyl ring and a butyl chain —forms the basis for many other chemicals containing various substituents .
Methyl vinyl ketone (MVK, IUPAC name: butenone) is the organic compound with the formula CH 3 C(O)CH=CH 2. It is a reactive compound classified as an enone , in fact the simplest example thereof. It is a colorless, flammable, highly toxic liquid with a pungent odor.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
C 2 H 4 + 1/ 2 O 2 → C 2 H 4 O. Alkenes react with ozone, leading to the scission of the double bond. The process is called ozonolysis. Often the reaction procedure includes a mild reductant, such as dimethylsulfide (SMe 2): RCH=CHR' + O 3 + SMe 2 → RCHO + R'CHO + O=SMe 2 R 2 C=CHR' + O 3 → R 2 CHO + R'CHO + O=SMe 2
The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. The di-, tri- etc. prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane).
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.
2-methylprop-1-ene In the chemical structures above, the small blue numbers in the structure images are the numbering of the atoms in the main backbone chain of the molecules. Other organic compounds have the formula C 4 H 8 , namely cyclobutane and methylcyclopropane , but are not alkenes and do not fall under the name butene .
