The molecule consists of a phenyl group (−C 6 H 5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause chemical burns. [5] Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 million tonnes a year) from petroleum-derived feedstocks.
In April 2011, two weeks after being reported missing, two men in northwestern Pennsylvania were found dead in a remote location on government land. The official cause of death of both men was hypothermia, but toxicology reports later confirmed that both Troy Johnson, 29, and Terry Sumrow, 28, had ingested MDPV shortly before their deaths. "It ...
Phenoptosis (from pheno: showing or demonstrating; ptosis: programmed death, "falling off") is a conception of the self-programmed death of an organism proposed by Vladimir Skulachev in 1999. In many species, including salmon and marsupial mice, under certain circumstances, especially following reproduction, an organism's genes will cause the ...
It adopts a T-shaped molecular geometry, with the phenyl group occupying one of the three equatorial positions of a trigonal bipyramid (lone pairs occupy the other two) and the axial positions occupied by oxygen atoms from the acetate groups. The "T" is distorted in that the phenyl-C to I to acetate-O bond angles are less than 90°. [1]
Phenylsilane is produced in two steps from Si(OEt) 4.In the first step, phenylmagnesium bromide is added to form Ph−Si(OEt) 3 via a Grignard reaction.Reduction of the resulting Ph−Si(OEt) 3 product with LiAlH 4 affords phenylsilane.
4-Phenylfentanyl is an opioid analgesic that is a derivative of fentanyl.It was developed during the course of research that ultimately resulted in super-potent opioid derivatives such as carfentanil, though it is a substantially less potent analogue. 4-Phenylfentanyl is around eight times the potency of fentanyl in analgesic tests on animals, but more complex 4-heteroaryl derivatives such as ...
The Times story also cited a buprenorphine study by researchers in Sweden that looked at “100 autopsies where buprenorphine had been detected.” According to the Times, the study found that “in two-thirds, it was the direct cause of death, mostly in combination with other drugs.” It was a misreading of the study.
Phenylmercuric nitrate is an organomercury compound with powerful antiseptic and antifungal effects. [1] It was once commonly used as a topical solution for disinfecting wounds, but as with all organomercury compounds it is highly toxic, especially to the kidneys, and is no longer used in this application.
