2-Phenylethyl bromide is an organobromide with the formula C 6 H 5 CH 2 CH 2 Br. It is a colorless liquid, although older samples appear yellow. Analogous to the preparation of most 1-bromoalkanes, it is prepared by free-radical addition of hydrogen bromide to styrene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo ...
2-Phenethyl bromide (C 6 H 5 CH 2 CH 2 Br) is produced via this route from styrene. Hydrogen bromide can also be used to convert alcohols to alkyl bromides. This reaction, that must be done under low temperature conditions, is employed in the industrial synthesis of allyl bromide: HOCH 2 CH=CH 2 + HBr → BrCH 2 CH=CH 2 + H 2 O

3-Methylfentanyl (3-MF, mefentanyl) is an opioid analgesic that is an analog of fentanyl. 3-Methylfentanyl is one of the most potent opioids, estimated to be between 400 and 6000 times stronger than morphine, [1] depending on which isomer is used (with the cis isomers being the more potent ones).
This is a list of fentanyl analogues (sometimes referred to as Fentalogs), [1] [2] [3] including both compounds developed by pharmaceutical companies for legitimate medical use, and those which have been sold as designer drugs and reported to national drug control agencies such as the DEA, or transnational agencies such as the EMCDDA and UNODC.
According to the International Monetary Fund, Sri Lanka's GDP in terms of purchasing power parity is second only to the Maldives in the South Asian region in terms of per capita income. As of 2010 [update] , the service sector makes up 60% of GDP, the industrial sector 28%, and the agriculture sector 12%. [ 1 ]
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H 3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically . It is a recognized ozone-depleting chemical.
It can be prepared by reacting ethylmagnesium bromide with methyl acetate in the so-called Grignard reaction using dried diethyl ether or tetrahydrofuran as solvent. Synthesis of 3-Methyl-3-pentanol. It can be prepared also by reacting ethylmagnesium bromide with butanone in the same conditions already mentioned.
