    摘要: The present invention provides cobalamin acid hydrazides of the general formula:B--CO--NH--NH--R--CO--NH--NH).sub.x H (I)wherein B is a residue formed from a cobalamin by the splitting off of a --CONH.sub.2 group, R is a spacer and x is 0 or 1, as well as a process for the preparation thereof.The present invention also provides cobalamin conjugates of the general formula:B--d--CO--NH--NH--R--CO--NH).sub.x N.dbd.GP (II)in which B, R and x have the above-given meanings and d signifies the position of --CO--NH--, as well as a process for the preparation thereof. These cobalamin conjugates are very suitable for use in immunoassays, especially for the determination of cyanocobalamin.
