Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 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 0 C═O and the alkoxycarbonyl radical R 0 --OC═O, where R 0 is a C 1 -C 6 alkyl, aryl selected from the class consisting of phenyl or naphthyl or aralkyl, said alkyl portion having 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 represent 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; and R 4 is selected from the group consisting of a quaternary ammonium ion and benzyl.
Claim 2
Dependent Claim
133 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 0 C═O and the alkoxycarbonyl radical R 0 --OC═O, where R 0 is a C 1 -C 6 alkyl, aryl selected from the class consisting of phenyl or naphthyl or aralkyl, said alkyl portion having 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 represent 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; and R 4 is selected from the group consisting of a quaternary ammonium ion and benzyl.
Claim 3
Dependent Claim
19 words
A compound in accordance with claim 1, wherein R 1 , R 2 and R 3 are all hydrogen.
Claim 4
Dependent Claim
