A dosing form for at least one solid reagent for use in conventional organic and inorganic synthesis, in parallel synthesis, and in split and mix synthesis in combinatorial chemistry is provided as compressed tablets each containing the same predetermined amount of said at least one reagent embedded in a polymer matrix comprising beads of a polymer insoluble in the solvents for the intended synthesis, which tablets are capable of disintegrating in said solvent for release of the at least one reagent and disperse the matrix as polymer beads into the solvent. The polymer beads forming the matrix and the reagents of the dosing form can easily be removed by filtration in order to separate these from a formed soluble product.
In a method for producing the dosing form, beads of one or more polymers are mixed with the reagents and compressed into tablets after pre-treatment with an aprotic organic solvent.
提供了一种用于传统有机和无机合成、并行合成以及在组合化学中的分割和混合合成中使用的至少一种固体试剂的剂型,其为每个压缩片剂,每个压缩片剂包含相同预定量的至少一种试剂,嵌入在聚合物基质中,该聚合物基质包括不溶于预定合成溶剂的聚合物珠,这些片剂能够在所述溶剂中解体以释放至少一种试剂,并将基质分散为聚合物珠进入溶剂中。剂型的聚合物珠形成基质和试剂可以通过过滤轻松地从形成的可溶产品中分离出来。
在生产该剂型的方法中,将一种或多种聚合物的珠与试剂混合,并在用无水有机溶剂预处理后压缩成片剂。
