Chemical Structure

DSPE-PEG4-acid CAS 2112738-58-4 chemical structure

Description

DSPE-PEG4-acid (CAS 2112738-58-4) is a high-purity analytical reference standard with the molecular formula C52H100NO15P and a molecular weight of 1010.32 g/mol.

The molecular framework of DSPE-PEG4-acid (C52H100NO15P) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures DSPE-PEG4-acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
