Preguntas frecuentes
Which formula is used?
The page uses the current ChemicalBook CAS-anchored PEG-average formula representation: (C2H4O)nC44H84NO12P.H3N.
Why is there no fixed molecular weight?
DSPE-PEG2000-COOH is treated as a PEG-average material in the current record, so fixed PubChem reference MW values are not used as the product specification.
