What is 3-Methoxypropionic acid?
Description
m-PEG1-acid is a PEG linker containing a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.
General Description
3-Methoxypropionic acid is an alkoxy acid. The base-catalyzed methanolysis of 1-nitroso-5,6-dihydrouracil, potent liver carcinogen, is reported to yield 3-methoxypropionic acid.
