Product Information

Description	SPDP-PEG9-NHS ester is a PEG-based PROTAC linker that has an amine-reactive N-hydroxysuccinimide (NHS) ester at one end and a sulfhydryl-reactive 2-pyridyldithiol group at the opposite end. This has a single molecular weight PEG spacer arm, which confers greater water solubility to the crosslinker and linked proteins compared to crosslinkers having only hydrocarbon spacers.
Synonyms	SPDP-dpeg(R)9-NHS ester; Opss-peg(9)-nhs; 2,5-dioxopyrrolidin-1-yl 2-((2-(3-(pyridin-2-yldisulfaneyl)propanamido)ethoxy)methyl)-3,6,9,12,15,18,21,24-octaoxahexacosanoate
IUPAC Name	(2,5-dioxopyrrolidin-1-yl) 3-[2-[2-[2-[2-[2-[2-[2-[2-[2-[3-(pyridin-2-yldisulfanyl)propanoylamino]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]propanoate
