Chemical fluoro

Several chemical methods have been devised for identifying the N terminal ammo acid They all take advantage of the fact that the N terminal ammo group is free and can act as a nucleophile The a ammo groups of all the other ammo acids are part of amide linkages are not free and are much less nucleophilic Sanger s method for N terminal residue analysis involves treating a peptide with 1 fluoro 2 4 dimtrobenzene which is very reactive toward nucleophilic aromatic substitution (Chapter 23)... [Pg.1131]

Carboxypeptidase catalyzed hydrolysis can be used to identify the C terminal ammo acid The N terminus is determined by chemical means One reagent used for this purpose is Sanger s reagent 1 fluoro 2 4 dimtrobenzene (see Figure 27 9)... [Pg.1151]

Difluoronaphthalene [315-52-6] is prepared from 4-fluoro-l-naphthylarnine by the Balz-Schiemann reaction. 1,4-Difluoronaphthalene is used in chemical carcinogenesis studies as a synthon for highly condensed difluoro—polycycHc aromatic hydrocarbons (273). [Pg.328]

In 1989 Du Pont introduced Teflon AF, said to be a copolymer of tetrafluoroethylene and trifluoromethyldifluorodioxol. This amorphous fluoro-polymer has a similar heat and chemical resistance to PTFE but possesses several notable properties, including ... [Pg.378]

Fluorine-19 NMR has also been used to study annular tautomerism in pyra-zoles, both for fluoro- and for trifluoromethyl-pyrazoles (99H355). Comparison of data chemical shifts and V coupling constants of 64a and 64b]... [Pg.42]
