SDP

m-PEG1-NHS ester is a methoxy-terminated PEG1 N-hydroxysuccinimide ester that provides an activated NHS ester for efficient coupling to primary amines. It is used as a short PEG linker in bioconjugation and PROTAC synthesis to introduce a flexible spacer and enable amide bond formation under mild conditions.

  • Provides a methoxy-terminated PEG1 spacer for minimal linker length.
  • Contains an active NHS ester for rapid amide coupling to primary amines.
  • Suitable for PROTAC linker assembly and general bioconjugation.
  • Available in multiple pack sizes for flexible scaling.
