Medchemexpress LLC Pomalidomide-PEG2-azide | 2267306-14-7 | MFCD32198604 | 96.6% | 444.40 g/mol | C19H20N6O7 | 5 MG
Pomalidomide-PEG2-azide is a pomalidomide-based cereblon (CRBN) ligand-linker conjugate featuring a two-unit polyethylene glycol spacer and an azide functional group. It is developed as a building block for targeted protein degrader (PROTAC) research and for modular conjugation via click chemistry, offering a balance of solubility and reactivity for medicinal chemistry applications.
- Provides a pomalidomide scaffold for CRBN recruitment.
- Two-unit PEG linker improves solubility and linker flexibility.
- Azide handle enables copper-catalyzed azide-alkyne cycloaddition (click chemistry).
- Suitable for use as a PROTAC building block and linker module.
- Available in small-scale quantities for medicinal chemistry and assay development.

Nanocs Palmitic acid PEG, mPEG-PLA, Specification: 5000 Da,100 mg
Palmitic acid is a 16 carbon saturated fatty acid lipid with excellent hydrophobicity. PEG modified palmitic acid is an excellent amphilphilic polymer with both hydrophilicity and hydrophobility. Pegylated lipids are excellent liposome formation materials that can be used for drug delivery, gene transfection and vaccine delivery as well. These materials can also be used for targeted drug delivery by modifying their surfaces with targeting ligands such as antibodies, peptide
Medchemexpress LLC NHS-PEG2-SS-PEG2-NHS | 96.7% | 580.63 g/mol | C22H32N2O12S2 | 5 MG
NHS-PEG2-SS-PEG2-NHS is a cleavable four-unit polyethylene glycol (PEG) linker with N-hydroxysuccinimide (NHS) ester end groups and a disulfide (SS) cleavable junction, supplied for use in antibody-drug conjugate synthesis and other bioconjugation applications.
- Cleavable disulfide bond enables reductive release of payloads.
- Hydrophilic PEG spacer improves solubility and reduces aggregation.
- NHS ester end groups provide rapid amine coupling to proteins.
- Moderate molecular weight supports spacer function without excessive steric bulk.
- Available in small research sizes suitable for conjugation optimization.
Medchemexpress LLC Dspe-peg-cooh | 98.1% | 5000 (Average) | 50 MG
DSPE-PEG-COOH (MW 5000) is a PEG lipid that can improve the delivery efficiency and tissue specificity of poorly soluble drugs. It can be used in drug delivery research.
- Improves delivery efficiency
- Enhances tissue specificity
- Suitable for drug delivery research
- PEG lipid
Medchemexpress LLC Dbco-peg4-val-cit-pab-pnp | 2226472-28-0 | 98.3% | 1079.16 | C55H66N8O15 | 100 MG
DBCO-PEG4-Val-Cit-PAB-PNP is a cleavable linker reagent designed for constructing antibody-drug conjugates and click-chemistry bioconjugates. It combines a strain-promoted alkyne-azide cycloaddition (DBCO) handle with a Val-Cit protease-cleavable dipeptide and a PAB-PNP leaving group to enable enzyme-triggered payload release and efficient payload attachment. The compound is supplied as a characterized solid for research use.
