Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
153 words
A disulfide of mercaptopyridine-1-oxide 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 portion having 1-6 carbons, or halobenzyl, the C 1 -6 alkane sulfonyl radical, the aralkanesulfonyl radical, and the arenesulfonyl radical ArSO 2 wherein the aryl radical may be substituted by a C 1 -C 6 alkyl, alkoxy and/or a halo-radical; 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, and 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.
Claim 2
Dependent Claim
