Description

Bis-Trityl-Peg13 CAS NO 2010151-26-3 is a high-purity, bifunctional polyethylene glycol (PEG) derivative featuring trityl-protected terminal hydroxyl groups. This compound is a critical building block in the synthesis of complex molecules, offering controlled conjugation and enhanced solubility. It is primarily utilized by researchers and manufacturers in the pharmaceutical, bioconjugation, and advanced materials sectors for developing novel therapeutics, drug delivery systems, and functional polymers.

Application

• Pharmaceutical Linker: Serves as a versatile, hydrophilic spacer in the synthesis of antibody-drug conjugates (ADCs), peptide-drug conjugates, and other biopharmaceuticals.
• Polymer Chemistry: Acts as a key monomer or initiator for creating precisely defined block copolymers and functionalized PEGs with specific chain lengths.
• Probe and Sensor Development: Used to modify surfaces or biomolecules with PEG chains to reduce non-specific binding and improve biocompatibility in diagnostic assays.
• Material Science: Employed in the fabrication of hydrogels, coatings, and nanomaterials where controlled hydrophilicity and functional group presentation are required.
• Organic Synthesis Intermediate: Provides a protected diol for selective reactions, enabling the stepwise construction of complex architectures in medicinal chemistry.
