Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A mercaptopyridine-1-oxide compound having the following structural formula: ##STR10## wherein R is selected from the group consisting of the acyl radical R o C═O and the alkoxycarbonyl radical R o -OC═O, where R o is a C 1 -C 6 alkyl, aryl selected from the class consisting of phenyl or naphthyl or aralkyl, said alkyl having portion 1-6 carbons or halobenzyl; R 1 , R 2 and R 3 are each independently selected from the group consisting of hydrogen, methyl, two of said terms may repreent methoxy and the other hydrogen, one of said terms may represent ethyl, n-butyl, methoxy, ethoxy, phenyl, bromophenyl, chlorophenyl, trichlorophenyl, naphthyl, chlorobenzyl, dichlorobenzyl or furyl and the other two terms represent hydrogen; R 4 is selected from the group consisting of hydrogen, an alkali metal, and an alkaline earth metal.
Claim 2
