Bromoacetamido-PEG4-NHS ester is a PEG linker containing a bromide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
(3-Hydroxymethyl)phenylboronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient construction of biaryl and heteroaryl architectures. The ortho-hydroxymethyl group offers additional functionality for downstream derivatization, while the boronic acid moiety provides excellent bench stability and compatibility with diverse reaction conditions. Its defined regiochemistry and predictable reactivity make it ideal for the synthesis of complex pharmaceutical intermediates and functional materials.
