Product Description

PROTAC Linker 25 is a PROTAC connection bridge of PEG class. PROTAC Linker 25 can be used to synthesize a series of PROTAC molecules. The PROTAC molecule contains two different ligands connected by a connecting bridge; one is an E3 ubiquitin ligase ligand and the other is a target protein ligand. PROTAC uses the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

Nature Description

Colorless, transparent and slightly sweet stable viscous liquid. Freezing point-7.2 ℃, melting point-4.3 ℃, boiling point 289.4 ℃,134 ℃(0.267kPa), relative density (15 ℃)1.1274, refractive index 1.4578(15 ℃), burning point 173.9 ℃, flash point 330 ℃ (closed Cup), ignition point 412.8 ℃, vapor pressure 1Pa(20 ℃). It is miscible with water, ethanol, benzene and toluene, insoluble in ethers and insoluble in petroleum ether. Hygroscopicity. It has oxygen atoms and hydroxyl groups connected with alkyl groups, so it has alcohols and ethers properties.
