Product Information

Description	mPEG-MAL is a maleimide functionalized PEG that reacts with a thiol (thiol/SH) group. It can be used to selectively modify proteins, peptides or any other surface. At pH 6.5-7.5, stable thioether bonds are more easily formed between maleimide and thiol.
Synonyms	mPEG-Maleimide
IUPAC Name	1-(2-methoxyethyl)pyrrole-2,5-dione
Canonical SMILES	COCCN1C(=O)C=CC1=O
InChI	InChI=1S/C7H9NO3/c1-11-5-4-8-6(9)2-3-7(8)10/h2-3H,4-5H2,1H3
InChIKey	ASUGWWOMVNVWAW-UHFFFAOYSA-N
Solubility	Soluble in water, DMSO and DMF. Freshly prepared before use.
Storage	-20°C for long-term preservation, keep in dry and avoid sunlight. Avoid repeated freezing and thawing.
