    摘要: A process for producing a polyoxyalkylene derivative substituted with succinimidyl group which comprises reacting a polyoxyalkylene compound having carboxyl group at ends with N-hydroxysuccinimide in an inert solvent in the presence of dicyclohexylcarbodiimide; filtering an obtained reaction product; and crystallizing the polyoxyalkylene derivative substituted with succinimidyl group by adding isopropyl alcohol to a filtrate obtained by the filtration, an amount by weight of isopropyl alcohol being 1 to 100 times as much as an amount by weight of the polyoxyalkylene compound having carboxyl group at ends. Materials can be handled with safety in the process of the present invention, and a highly pure polyoxyalkylene derivative substituted with succinimidyl group which does not cause turbidity in an aqueous solution and has an excellent quality as a material for drugs can be produced.

    摘要: An object the invention is to provide a method of analyzing the activation ratio of terminals of a polyoxyalkylene derivative so that the ratio can be accurately measured at a high precision even when the polyoxyalkylene derivative has a high molecular weight. The activation ratio of terminal of a polyoxyalkylene derivative having a terminal active group capable of bonding with a biologically active substance having a molecular weight of 1000 to 100000 is analyzed. The active group is labeled using a labeling reagent having an ionic functional group. The polyoxyalkylene derivative is then analyzed by means of liquid chromatography using an ion-exchange column and an RI detector outputting a chromatogram. The activation ratio of terminal is obtained based on percentage of an area of a peak corresponding to the active group in the chromatogram.

    摘要: A process for producing a polyoxyalkylene derivative substituted with succinimidyl group which comprises reacting a polyoxyalkylene compound having carboxyl group at ends with N-hydroxysuccinimide in an inert solvent in the presence of dicyclohexylcarbodiimide; dissolving an obtained reaction product into chloroform, an amount by weight of chloroform being 0.5 to 10 times as much as an amount by weight of the polyoxyalkylene compound having carboxyl group at ends; and crystallizing the polyoxyalkylene derivative substituted with succinimidyl group by adding an aliphatic hydrocarbon having 5 to 8 carbon atoms to a resultant solution, an amount by weight of the aliphatic hydrocarbon being 2 to 10 times as much as an amount by weight of chloroform. Materials can be handled with safety, and a highly pure polyoxyalkylene derivative substituted with succinimidyl group which does not cause turbidity in an aqueous solution and has an excellent quality as a material for drugs can be produced.
