Medchemexpress LLC S-acetyl-dPEG8-NHS ester | 1070798-99-0 | MFCD11041104 | 99.6% | 597.67 g·mol⁻¹ | C25H43NO13S | 25 MG
Supplier: Medchemexpress LLC HYW19076625MG
S-acetyl-dPEG8-NHS ester is a discrete polyethylene glycol bifunctional reagent designed to introduce a protected thiol into biomolecules. The NHS ester end selectively reacts with primary amines to form stable amide bonds, while the S-acetyl group can be removed to reveal a free thiol for downstream conjugation or cross-linking. The single-molecule PEG spacer provides defined length and improved solubility, enabling controlled labeling and linker construction in bioconjugation workflows.
- Provides defined PEG spacer (n = 8) for controlled spacing.
- Contains an NHS ester for conjugation to primary amines.
- Has an S-acetyl protected thiol that can be deprotected to expose a free thiol.
- Improves solubility and reduces nonspecific binding.
- Suitable for protein labeling, bioconjugation, and linker synthesis.
