Additional material information
Characteristics
- DSPE phospholipid anchor connected with PEG2000 maleimide functionality.
- CAS 474922-22-0 is indexed by ChemicalBook under DSPE-PEG-Mal and DSPE-PEG(2000) Maleimide names.
- PubChem provides fixed reference records, so formula and molecular-weight comparisons should preserve the PEG-average convention.

Frequently Asked Questions
Why is the product described as an average-material entry?
ChemicalBook lists a PEG-distribution formula for DSPE-PEG-Mal, while PubChem uses fixed reference records; the page therefore keeps the PEG2000 material convention explicit.
