摘要:The present invention relates to chemical synthesis and purification. Specifically, the present invention relates to a process for preparation of highly pure, moisture free crystalline fluorescein sodium in freeflowing powder form. More particularly, the process relates to synthesis of crystalline fluorescein sodium from diacetyl-fluorescein or fluorescein without using water or aqueous solvents.

摘要:Dye-labeled polymers formed from a polymer and a dye are disclosed. Methods for labeling a polymer with a dye are also disclosed. The polymer can have any weight average molecular weight (Mw), particularly a Mw of >5 megadalton (MDa) or >6 MDa. The polymer contains reactive group(s) that can be activated by an activation agent in a buffer solution. Upon activation, the polymer bundles and forms activated polymer in a solid form. The activated polymer can react with a reactive group of the dye to form the dye-labeled polymer. By soaking the dye-labeled polymer in a solid form in an aqueous solvent, the dye-labeled polymer can regain the viscosifying property that is the same or substantially the same as the polymer prior to labeling with the dye.
