Chemical Structure

N-Mal-N-bis(PEG2-amine) CAS 2128735-20-4 chemical structure

Description

CATO supplies N-Mal-N-bis(PEG2-amine) (CAS 2128735-20-4), a certified reference material (molecular formula C19H34N4O7, MW 430.50 g/mol) for analytical method development and quality control.

The molecular framework of N-Mal-N-bis(PEG2-amine) (C19H34N4O7) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 N-Mal-N-bis(PEG2-amine) 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.
