phenoxy การใช้

• These species feature a 2-aminomethylfuran linked to phenoxy group.
• Phenoxy compounds tend to selectively kill broad-leaf weeds rather than grasses.
• Categorized as a polychloro phenoxy phenol, triclosan is a M sodium hydroxide solution, but only slightly soluble in water.
• Furthermore, waterhemp at a site in Nebraska was found to be resistant to 2, 4-D, a phenoxy herbicide.
• It is an important industrial commodity as a epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs.
• Phenoxy herbicides are often contaminated with TCDD; research has suggested such contamination results in a small rise in cancer risk after occupational exposure to these herbicides.
• "' 2, 4-Dinitrophenylmorphine "'is an analog of morphine in which a hydroxyl group is substituted with a dinitro phenoxy group.
• The phenoxy and benzoic acid herbicides function similar to plant growth hormones, and grow cells without normal cell division, crushing the plant's nutrient transport system.
• The unsubstituted molecule is a weak SSRI . A compound highly potent and selective for blocking norepinephrine reuptake, a SNRI, results from 2-substitutions into the phenoxy ring.
• Tadimety Aromatics manufactures over 100 aroma chemicals including cuminic nitrile, caryophyllene acetate, herbox, hydrotropal, phenoxy ethyl isobutyrate, rhuboxide ( rhubafuran ), tremone, and woodol.
• But it was just another day for the Food and Drug Administration's Advisory Committee on Special Studies Relating to the Possible Long-Term Health Effects of Phenoxy Herbicides and Contaminants.
• Related to alkoxy groups are "'aryloxy "'groups, which have an aryl group singular bonded to oxygen such as the phenoxy group ( C 6 H 5 O ).
• Agent Green's only active ingredient was 2, 4, 5-trichlorophenoxyacetic acid ( 2, 4, 5-T ), one of the common phenoxy herbicides of the era.
• Agent Pink's only active ingredient was 2, 4, 5-trichlorophenoxyacetic acid ( 2, 4, 5-T ), one of the common phenoxy herbicides of the era.
• In California, it has become a significant problem in this way because of the restrictions on phenoxy herbicides being used in the state due to crops such as the sensitivity of cotton and grapes to this chemical.
• During the legislative session in 2012, Castelli authored and passed a bill to extend the statute of limitations for Vietnam Veterans to bring claims arising from exposure to Agent Orange and other phenoxy herbicides, which was signed into law by Governor Cuomo.
• It was known at that time that the antihistamine diphenhydramine shows some antidepressant-like properties . 3-Phenoxy-3-phenylpropylamine, a compound structurally similar to diphenhydramine, was taken as a starting point, and Molloy synthesized dozens of its derivatives.
• The first drug, clomifene ( 2-[ 4-( 2-chloro-1, 2-diphenylethenyl ) phenoxy ]-N, N-diethylethanamine; 2-hydroxy-1, 2, 3-propanetricarboxylate; see figure 6 ) has a chloro-substituent on the ethylene side chain which produces similar binding affinities as the later discovered drug tamoxifen.
• A second Norrish reaction then adds another C C bond to alcohol "'23 "'and having served its purpose the phenoxy tail is removed in several steps : a Birch reduction to diol "'24 "', oxidation with pyridinium chlorochromate to ketoaldehyde "'25 "'and a reverse Claisen condensation to ketone "'26 " '.
• Hydrogels can be classified according their polymers constituents, which can be natural ( Hyaluronan, alginic acid, pectin,, chondroitin sulfate, dextran and dextran sulphate, chitosan, polylysine, collagen, carboxymethyl chitin, fibrin, agarose, pullulan ), or synthetic ( PVA, PNVP, P ( HEMA ), p ( biscarboxy-phenoxy-phosphazene ), p ( GEMA-sulfate ), and others ), or a hybrid of the two.
