For professionals in chemical research and development, understanding the precise chemical properties of intermediates is crucial for successful synthesis and application. HO-PEG-NH2 (CAS 32130-27-1), a derivative of polyethylene glycol, presents a fascinating combination of structural features that lend it significant versatility. As a dedicated supplier of specialty chemicals, we are pleased to offer insights into this valuable compound.

At its core, HO-PEG-NH2 is a hydrophilic polymer. Its backbone consists of repeating oxyethylene units, giving it excellent solubility in water and many polar organic solvents. The defining characteristic, however, is the presence of a terminal amino group on one end and a hydroxyl group on the other, making it a heterobifunctional molecule. This structure allows for diverse chemical reactions. The amino group is a nucleophile and can readily react with electrophiles such as carboxylic acids (forming amides), aldehydes and ketones (forming imines), and activated esters like N-hydroxysuccinimide (NHS) esters. This reactivity makes HO-PEG-NH2 a prime candidate for conjugation chemistries, a common practice in fields ranging from bioconjugation to materials science.

When considering purchasing HO-PEG-NH2, understanding its molecular weight distribution and purity is important, as these factors directly influence its performance. Our role as a manufacturer in China is to provide this compound with consistent quality and well-defined specifications, supporting researchers and formulators. Whether you are exploring its use as a linker, a surface modifier, or a building block for complex structures, the chemical reactivity of HO-PEG-NH2 is a key asset.
