Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
A compound of the formula ##STR3## wherein A is a monofunctional diazole or thiazole radical selected from the group consisting of a 1-N-methylpyrazole radical which is bonded to the cyclohexadien-1-one ring via a carbon atom which is alpha to a nitrogen atom of the pyrazole ring, a 1-N-methylimidazole radical which is bonded to the cyclohexadien-1-one ring via a carbon atom which is alpha to a nitrogen atom of the imidazole ring, and a thiazole radical which may be optionally substituted by a single halogen or methyl radical.
Claim 2
Dependent Claim
87 words
