摘要:
The invention relates to a process for the production of diethylenetriaminepentacarboxylic acid tetraesters of general formula I ##STR1## in which R.sup.1 and Z have different meanings.
摘要:
The invention relates to intermediate products and a new process for the production of benzocycloheptene C. The process for the production of its new intermediate products according to the invention starts from economical starting materials, provides the intermediate stages in high yields and high purity, without chromatographic purification steps, and allows production on an industrial scale.
摘要:
The invention relates to radioactive stents, characterized in that the stent is coated on the surface with the radioactive isotope, as well as processes for their production.
摘要:
A new process for the production of triiodotrimesic acid that is used as an intermediate product for the synthesis of x-ray contrast media is described.
摘要:
The invention relates to new, monomeric, perfluoroalkyl-substituted metal complexes, processes for their production, and their use in diagnosis and therapy.The compounds according to the invention are suitable especially as in vivo contrast media in nuclear spin tomography (MRT). They can preferably be used as blood-pool agents and as lymphographic agents.
