Description

Fd&Cblueno.1Pegderivative CAS NO 9079-33-8 is a polyethylene glycol (PEG) derivative of the certified food colorant FD&C Blue No. 1 (Brilliant Blue FCF). This modification enhances the molecule's solubility and stability in aqueous and specific formulation systems, making it a valuable functional ingredient. It is primarily sought after by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical sectors who require advanced colorants with tailored physical properties. This product offers a solution for creating stable, uniformly colored products where standard dyes may present formulation challenges.

Application

• As a colorant and tracer in pharmaceutical tablet coatings and capsule formulations.
• In the development of diagnostic reagents and test kits where visual color change is critical.
• For coloring research media and biological stains in life science laboratories.
• As a specialized pigment in high-value industrial inks and coatings.
• In the formulation of colored contact lenses and other ophthalmic products.
• As a model compound for studying PEGylation chemistry and dye-polymer interactions.
