Another method used for nitrate determination on dried and milled herbage employs the nitrate selective electrode. One of the first published methods was that of Paul and Carlson (1968). Other anions, especially chloride, can interfere. These authors removed chloride with silver resin, but Barker ef al. (1971) omitted the resin because it tended to foul the electrode and cause excessive drift. Normally the Cl N03 ratio is so low as not to interfere, but saline precipitation from coastal plots could affect this. The method was further modified to allow storage of extracts for up to 64 h by adding a preservative of phenyl-mercuric acetate and dioxane, both very toxic (Baker and Smith, 1969). This paper mentions the need to change the electrode s membrane, filling solution and liquid ion exchanger every 2 months to minimize chloride interference. It is easy to overlook electrode maintenance between batches of nitrate analyses, and this can lead to errors and sluggish performance. 

In spite of its toxicity, derivatives of phenyl mercuric acetate having substituents such as thiohydantoins in the aromatic ring are still being studied as fungicides and bactericides.144"147... 

Metallic catalysts will cause rapid poisoning if ingested. Some catalysts— for example, phenyl mercuric acetate—will result in strong caustic burning. Contact with the skin will cause a dangerous burn. Care must be taken with these materials even though they are only used in very small quantities. These catalysts are extremely toxic if digested. 

Mercury diphenyl has been prepared in a number of ways. The most important methods are by the action of sodium on a mixture of bromobcnzene and mercuric chloride 1 from sodium amalgam and phenyl mercuric iodide 2 by the interaction of phenyl mercuric bromide and potassium sulfide2 or phenyl mercuric acetate and sodium stannite 3 from phenyl magnesium bromide and mercuric chloride 4 by the action of phenyl hydrazine on mercury compounds 5 from mercuric chloride and phenyl arsenious oxide 6 and from diphenyl mercuric ammonium acetate and sulfur compounds.7... 

Enzyme assays were conducted in a 10 mL screw-neck glass test tube containing 100 fiL of lysate, 90 fiL of a 250 /ng/mL solution of 6-mercaptopurine in 0.01 M HC1, and 15 /uL of 250 mM sodium phosphate buffer (pH 9.2). Reactions were initiated by the addition of 32 fiL of a 3 1 mixture of 250 fiM S-adenosyl-L-methionine and 30 mM dithiothreitol. The final pH was 7.5. After a 1-hour incubation at 37°C, the reaction was stopped by the addition of 850 fjL of ice-cold 3.5 mM dithiothreitol and 50 fih of 1.5 M H2S04. The tubes were then heated at 100°C for 2 hours. To each tube, 500 fiL of 3.4 M NaOH was added, immediately followed by 8 mL of toluene-amyl alcohol-phenyl mercuric acetate. The tubes were shaken for 10 minutes and centrifuged. Then 6 mL of the toluene layer was transferred to a glass-stoppered conical test tube and 0.2 mL of 0.1 M HC1 added. After vortex-mixing and centrifuging, the toluene layer was discarded. Samples (50 fiL in 0.1 M HC1) were used for HPLC analysis. Product formation was linear for up to 120 minutes and 150 /u,L of lysate. 

The thiols in the native enzyme are remarkable unreactive except with mercurials 150, 164) and with cupric ion 164, 1S6, 165). Two thiols react rapidly with phenyl mercuric acetate and 2 more slowly. Reduction of mercurial treated enzyme (after removal of excess reagent) by NADH results in the migration of phenyl mercury to the nascent thiols of the active center 160). 

Glutathione reductase from yeast and from E. coli contains 4 and 6 thiol groups per FAD, respectively (Table I), in addition to the active center disulfide. Peptides containing 3 of the 4 thiols have been isolated and sequenced Cys-AsnAsp Lys-Ile-Ala-Cys-Pro-Gly-Asn-Val-Gln-Lys Asp-Thr-Ile-Tyr- (His,Glx) -Val-Cys-Lys- (Thr,Gly,Ala,Leu2) (35). The thiols in the yeast enzyme, like those in lipoamide dehydrogenase, are relatively unreactive. Reactivity with phenyl mercuric acetate...

The arylation of enol esters has also been improved (95). Previously a wide range of products were produced including j8-aryl carbonyls, arylated enol esters, styrene, and stilbene derivatives (96). It has also been found that arylated enol esters can be obtained as major products if the reactions are carried out with stoichiometric amounts of aryl mercuric acetate and palladium acetate in anhydrous acetonitrile or in excess enol ester solution. The products are those arising from addition of the phenyl group to the carbons not containing the ester. Thus, with vinyl acetate and phenyl mercuric acetate, the product is the enol acetate of phenyl acetaldehyde ... 

Infants exposed to diapers that had been treated with a phenylmercury fungicide exhibited higher urinary levels of mercury than unexposed infants (Gotelli et al. 1985). In rats, dermal absorption of phenyl-mercuric acetate from the vaginal tract was 75% of the dose within 8 hours after administration (Laug and Kunze 1949).

Ethyl lactate is used as a high-boiling solvent for cellulose ether [66]. Phenyl mercuric lactate is obtained by reacting phenyl mercuric acetate with lactic acid. It is used in slime control of paper stock [67].
