Abstract: The invention relates to novel dimaleinimido-substituted dihydroxyalkanes, to a process for their preparation as well as to their use as cross-linking reagents, e.g. in analytical methods. A disadvantage of the cleavable bismaleinimido derivatives used so far, which react with SH groups, is that the subsequent cleavage of the cross-linking reagents from the proteins must take place in acidic or alkaline media. The objective of the invention is to prepare novel cleavable cross-linking reagents which react with SH groups or proteins and which form cross-links which can be cleaved under mild conditions not requiring strongly acidic or basic media. This objective is sought through the preparation and use of dimaleinimido-substituted dihydroxyalkanes having the general formula I ##STR1## where n=1 to 6, preferably 1 or 2.
