CAS 1415800-38-2

Bromo-PEG5-t-butyl ester

Description:

Bromo-PEG5-t-butyl ester, with the CAS number 1415800-38-2, is a chemical compound that belongs to the class of polyethylene glycol (PEG) derivatives. It features a bromo substituent, which enhances its reactivity and potential for further chemical modifications. The "PEG5" indicates that the compound has a polyethylene glycol chain consisting of five repeating ethylene glycol units, contributing to its hydrophilicity and solubility in aqueous environments. The t-butyl ester group provides steric hindrance, which can influence the compound's reactivity and stability. This compound is often utilized in bioconjugation and drug delivery applications due to its ability to form stable linkages with various biomolecules. Its characteristics include moderate molecular weight, good solubility in polar solvents, and potential for functionalization, making it a versatile building block in synthetic chemistry and pharmaceutical development. Safety and handling precautions should be observed, as with any chemical, to mitigate risks associated with its use.

Br-PEG5-CH2CH2COOtBu

CAS: 1415800-38-2

Br-PEG5-CH2CH2COOtBu is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Br-PEG5-CH2CH2COOtBu is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.
