m-PEG-NHS ester (average MW 20,000) is a methoxy-terminated polyethylene glycol bearing an N-hydroxysuccinimide (NHS) ester functional group. It is designed for research use to introduce PEG chains onto amine-containing molecules, enabling PEGylation, bioconjugation, and use as a PEG-based linker for tasks such as PROTAC synthesis.

  • Methoxy-terminated PEG with NHS ester for efficient amine coupling.
  • Average molecular weight 20,000 for extended linker length and solubility enhancement.
  • High purity (98.0%) suitable for research applications.
  • Soluble in DMSO at approximately 175 mg/mL (ultrasonic recommended).
  • Store sealed away from moisture and light at -20°C; in solvent store at -80°C for up to 6 months.
  • Intended for research use only; not validated for medical applications.
