ABSTRACT:
The sulfonamide derivative according to the present invention is expressed by a general formula: ##STR1## (where R represents an alkyl group. --X represents --L.sub.12 --COOM or ##STR2## and Y-- represents R--SO.sub.2 NH--L.sub.11 -- or MOOC--L.sub.12 --. Each of L.sub.11 and L.sub.12 represents an alkylene group. Z is identical to Y, and M represents a hydrogen atom or a cation. However, X and Y cannot be --L.sub.12 --COOM at the same time. W represents an alkylene group or a cycloalkylene group having 2 or more carbon atoms.)
This compound is useful as a metallic ion shielding agent and is suitable, for example, for the applications such as photographic processing solution, chelate titration or analytical reagent for medical treatment or for medical drugs as a metallic ion shielding agent.
